How To Keep Pond Water Clear Without A Filter

How to Keep a Pond Clean Without a Filter (Step-by-Step Guide)

Aspects of use: Controls algae growth, increases oxygen content, and aids in the removal of excess nutrients from water. Plants are excellent natural filters, capturing and using surplus nutrients that might contribute to water clarity problems. Adding pond plants is one of the most effective long-term methods of keeping pond water healthy and clean; and the more plants you can add, the better the results! In fact, for a wildlife pond without a filter, we recommend that at least 60% of your pond be filled with pond plants in order to get the greatest advantages.

Due to the fact that plants absorb nutrients and cover a huge area of surface water, they will compete with nuisance algae and serve to prevent weeds from developing uncontrollably.

Additionally, by eliminating excess nutrients from the water, the water will be less murky overall.

Aside from providing an aesthetic advantage, plants will also attract animals, such as frogs, newts, and insects, which will aid in the revitalization of a natural pond in the absence of fish.

Only submerged plants will assist to oxygenate the water, but all plants will aid in the reduction of excess nutrients and the removal of dangerous compounds from the water.

2)Provide OxygenationAeration

Benefits include the addition of oxygen, the creation of surface movement, the improvement of good microorganisms, and the deterrence of mosquitoes. Air pumps give a direct channel of oxygen to pond water and are therefore beneficial even if a filtration system is not included in the system. It is unlikely that you will have much aeration if you do not have a pump powering your filtration system, which may be quite hazardous for both animals and fish. Importantly, beneficial bacteria that are found at the core of a pond’s biological filtering system require huge levels of oxygen in order to function properly.

This second type of bacteria has the disadvantage of being slow digesters, which means they will not be able to break down waste at a fast enough rate.

Apart from that, algae may quickly grow in a stagnant pond, and mosquitoes prefer to lay their eggs in slow flowing water – all of which you should strive to prevent if you want a pond that is clean.

Adding more oxygen will allow good bacteria to thrive, allowing them to perform their functions more effectively, and the increased surface agitation will help prevent algae and mosquitoes from making your pond their permanent residence.

Adding aeration to your filterless pond is especially crucial if you have goldfish in the pond, as they will be vying with beneficial bacteria for dissolved oxygen on a regular basis. The greater the amount of oxygen you can supply to your waters, the more content they will be in their surroundings.

3)Supplement with Beneficial Bacteria

Benefits: Increases the population of beneficial bacteria, which enhances bio-filtration and helps to minimize waste. Beneficial bacteria treatments assist in increasing natural populations while also reducing trash. Among the functions of beneficial bacteria is the breakdown of hazardous chemicals such as ammonia and nitrites into less harmful nitrates, which are then utilized by plants as fertilizer. This process is referred to as the nitrogen cycle, and it will occur in any pond that contains enough oxygen, organic waste, and space for bacteria to colonize.

  • If you had a filter, they would quickly load the highly specialized filter media, allowing contaminants that pass through to be readily broken down, resulting in cleaner water being returned to the pond.
  • Bacteria will require a little amount of waste to survive (that is what they consume for nutrition), therefore entirely sterilizing a pond will have a negative impact on biological filtration.
  • In ponds without fish, a tiny quantity of sludge is actually useful because it supplies microorganisms with an energy source, plants with nutrients, and fauna, such as newts, with a safe haven to hide from predators.
  • We only advocate doing this 1-2 times a year, with the optimal periods being early spring and early fall, when debris is beginning to accumulate again after a long winter.

4)Remove Excess Bottom Muck

Beneficial effects include the reduction of surplus nutrients, the control of algae development, and the removal of tannin-producing debris. Water vacuums are the most efficient method of removing muck and sludge from the bottom of a pond liner. Small amounts of sludge are beneficial to the health of a wildlife pond because it offers nutrients for bacteria and plants, while also providing a hiding spot for frogs and newts. When the trash levels in a pond surpass the capability of the pond’s biological filtering system, the eco-system begins to suffer as the oxygen concentration in the water decreases and the water quality suffers.

  • The presence of sludge will not make water unclean, and a tiny quantity can actually help to clean it, but it is important to monitor it at least once every few months to ensure your pond is clear of algae, has sufficient oxygen, and that beneficial bacteria are not overpowered.
  • If you have a tiny pond, you may use a pond net to carefully scrape off the bottom muck anytime the level of the water becomes too high.
  • A pond vacuum will make short work of all types of trash and will save time and effort.
  • Installing a high-quality pond net is recommended as a preventative measure since it will help collect fallen leaves and twigs before they can sink into the pond and contribute to sludge buildup.

Because fish are most susceptible during the winter months, the optimum time to clean a pond of sludge is towards the conclusion of the fall season in preparation for the winter months when ponds freeze over.

5)Perform Water Changes(If you have fish)

Beneficial effects include the reduction of surplus nutrients, the control of algae development, and the removal of tannin-producing debris. Activated carbon hose attachments can assist in the removal of chlorine from water while changing the water. If you have a small number of fish in your pond and don’t have a filter in place, changing the water on a regular basis might be the most convenient approach to maintain water quality and increase clarity. Water changes will typically be between 10 and 30 percent of the total volume of water in the tank, and may be accomplished by emptying the upper levels of water into the garden with a pump, vacuum, or siphon hose.

  • Instead, we recommend that you use it to water your garden plants, as it functions as an excellent fertilizer!
  • Water changes are also particularly successful in removing tannin (color) from the water.
  • However, they can be useful in a pinch while you work on resolving the underlying issues.
  • To add insult to injury, the water supplied by our municipal water system contains high concentrations of chlorine and chloramine, both of which are very hazardous to aquatic life.
  • Treatments involving ode-chlorination.
  • A filter in your pond would be appropriate depending on the type of fish you keep, the size of the pond, and the total biological load (waste levels) present in the pond.
  • A large portion of the bio-load in a pond with fish would be generated by the fish themselves, which would be created on a continuous basis from fish excrement and during feeding.
  • Due to the fact that helpful bacteria are at the core of the filtering process, they are responsible for breaking down toxic compounds into less dangerous components, which is referred to as the nitrogen cycle, as explained above.
  • While on the other hand, the bio-load in a pond with just little fish or none at all will be relatively minor, therefore healthy water may occasionally be maintained with careful management and natural biological filtration (bacteria).

Using plants as natural water filters, frequent water changes, bacteria supplements, and periodic cleaning can sometimes be sufficient to maintain the cleanliness of a pond when no filter is present.

Keeping Fish in a Pond without a Filter System (Do’sDon’ts)

A filter-less pond is frequently sufficient for little fish, but large fish, such as koi, would require a separate filter system. Before we go any further into this issue, it should be noted that if you have fish in your pond, we always advocate installing a specific filter system. Even if your water quality is excellent and your fish appear to be in good condition, the difficulty with ponds is that they are susceptible to unexpected fluctuations in water quality, which can have a severe influence on the fish.

  • It is the responsibility of pond plants to guarantee that excess nutrients and dangerous chemicals are absorbed, while also striving to keep nuisance algae and weeds at bay.
  • The results of your water testing in your lightly-stocked fish pond indicate that all parameters (ammonium, nitrites, pH) are below acceptable limits, indicating that you are maintaining a safe environment for fish keeping!
  • A filtration system is almost always required in ponds with a high number of goldfish or larger koi in order to keep up with the biological load produced by the fish.
  • Adding a filter will provide you with additional peace of mind and will assist to protect your pond from harmful fluctuations, resulting in water quality that is more consistent and healthier.

Maintaining Clear Pond Water Without a Filter Box

A filter-less pond is generally sufficient for little fish, but larger species, such as koi, would require a separate filter system. Firstly, it should be emphasized that if you have fish in your pond, we always recommend that you install a specific filtration system to remove waste. However, even if the water quality is excellent and your fish appear to be in good condition, the difficulty with ponds is that they are susceptible to unexpected fluctuations in water quality, which can have a severe influence on the fish population.

Pond plants will guarantee that excess nutrients and dangerous compounds are absorbed, while also helping to keep nuisance algae and weeds at bay, according to the EPA.

If water tests in your sparsely populated fish pond show that ammonia, nitrites, and pH levels are below acceptable ranges, you are maintaining a safe environment for fish keeping!

To keep up with the biological load produced by goldfish and bigger koi, it is virtually always necessary to install a filtration system in a pond.

A filter will provide you with additional peace of mind and will assist you in protecting your pond from potentially harmful fluctuations, resulting in water quality that is more steady and nutritious.

Eco Filtration – Are Bog Filters (Plant Filters) Worth it?

Using natural pond plants as filter media, bog filters aid in the removal of hazardous chemicals from pond water. Instead of a standard filter in your pond, if you dislike the notion of a regular filter but still want to increase the quality and purity of your water, you may try installing a bog filter instead. An alternative form of filter, this one works by gently pushing water through a concentrated area of plants, which will work to absorb contaminants as the water passes through. It is more natural in its operation.

  1. However, because of the increased concentration of plants and the adjusted water flow, bog filters provide superior overall filtering.
  2. Bog filters will not be sufficient for the filtering needs of well stocked ponds or koi ponds; thus, in these instances, a normal filtration system would still be required for installation.
  3. Unfortunately, if you are unable to install a conventional filter owing to technical constraints, such as a lack of access to power, even a bog filter may not be an option for you.
  4. In cases where there is no access to power, it is frequently preferable to forego the inclusion of fish and instead create a wildlife pond, which will still look fantastic while also attracting frogs, newts, and a variety of insects!

How To Keep Pond Water Clear Without A Filter

Whether or whether you utilize a filter, the actions outlined below will assist you in maintaining clean and clear water. In reality, even in ponds equipped with filters, we recommend that the majority of these tasks be completed. In ponds without filters, on the other hand, you may have to repeat some of the stages more frequently. So, here’s how to maintain pond water pure without the use of a filter or any other artificial means.

1. Natural Pond Filter Plants

Pond plants are one of the most effective methods of organically filtering your pond water! They may eliminate any toxic chemicals from your pond or water garden by absorbing excess nutrients, aiding in oxygenation, and aerating the water. Algae and weeds require nutrients in order to grow and flourish. Furthermore, pond plants assist in consuming surplus nutrients, preventing algae and pond weeds from becoming out of control. The oxygen given by pond plants will not only aid in the survival and growth of your fish, but it will also aid in the growth of good bacteria, which in turn will aid in the breakdown of waste.

If you want the finest results, make sure to fill your pond with a variety of floating, emergent, and submerged oxygenating pond plants.

Benefits of Pond Plants

  • The plant adds oxygen to the water of your pond, consumes surplus nutrients, aids in algae management, protects the fish and blocks sunlight.

2. Pond Aeration

As well as providing oxygen to your fish, pond aeration may also aid in the maintenance of a clean and clear pond without the need of a filter! It accomplishes this by increasing the numbers of good bacteria in your pond (which require a lot of oxygen to exist), which will aid in the breakdown of waste in your pond and the reduction of the quantity of pond muck produced. Additionally, a pond aerator will aid in the circulation of water on the surface of your pond, which will successfully prevent mosquitoes from reproducing in your pond and prevent algae from overwhelming the surface of your water feature.

Benefits of Pond Aeration

  • Provides essential oxygen to the pond
  • Increases the amount of beneficial microorganisms in the pond
  • Causes surface movement
  • And repels mosquitoes.

3. Debris Removal

We won’t be utilizing a pond filter, so we’ll have to find another way to remove any trash and muck that has built in our pond before we can use it. And we’re talking about any floating garbage as well as debris that has already sunk to the bottom and will undoubtedly turn into sludge in the future. A small amount of sludge on the bottom of your pond isn’t a major deal (and can even serve as a source of nutrients for beneficial bacteria and plants), but it must be kept under control at all times.

Using a pond vacuum to remove pond sludge and debris is the quickest and most effective method of removal.

To clear waste from a pond, a telescopic pond net or a pond rake can be used as a more laborious method.

An wonderful tool for clearing trash and weeds from your pond, but it may not be the ideal choice for cleaning sludge since the tines might penetrate your pond’s liner if used improperly.

Benefits of Debris Removal

  • Reduces excess nutrients
  • Reduces pond muck
  • Aids in the preservation of oxygen levels
  • And more. Controls pond algae growth and aids in keeping water clean.

4. Perform Water Changes

If you have a fish pond, regular water changes are an excellent strategy to minimize surplus nutrients and hazardous compounds (such as ammonia and nitrites) that may quickly accumulate in the water. When you execute a water change, you are effectively replacing up to 25 to 30% of the water in your pond’s total volume with fresh water (use ourpond calculatorto figure out the volume of your pond). Candraining a pond can be accomplished with a pond vacuum, your pond’s pump, or a siphon hose. In addition, because pond water is high in nutrients, it may be used as a natural fertilizer by draining it into your garden or around plants and trees.

Using a pond dechlorinator, you may eliminate chlorine and chloramine from your tap water supply.

Benefits of Water Changes

  • Reduce the amount of nutrients and hazardous elements in your diet. Increase the purity of the water
  • Controls the growth of algae.

5. Beneficial Bacteria

Your pond’s nitrogen cycle is greatly aided by the presence of beneficial microorganisms in it. Essentially, this sort of “good” bacteria is responsible for the breakdown of ammonia, nitrites, and other toxic compounds into nitrates, which are then eaten by aquatic plants as an energy source. Provide an enough substrate for helpful bacteria to thrive on as well as sufficient oxygen in your pond through aeration to maximize the amount of beneficial bacteria present. In order to ensure that your beneficial bacteria levels continue to develop, make sure that you have an abundance of all of these items in your pond.

Because we will not be utilizing biological filter media (remember, we will not be using a filter), we may help replenish the bacteria levels in your pond by using abeneficial pond bacteriaproduct to do so.

No, but if you aren’t planning on using a filter (in which beneficial bacteria aids in the breakdown of debris as it passes through your bio-filter), you might want to consider these products as a way to ensure that your bacteria levels remain high and that they are able to perform their jobs to their full potential.

Benefits of Beneficial Bacteria Products

  • Increase the quantities of beneficial microorganisms in the environment
  • Reduce trash
  • Improve the purity and cleanliness of water

Additional Tips

The five methods outlined above will assist you in keeping your pond clean and clear without the need of a filtration system. However, we have a few more suggestions to assist guarantee that your pond has the finest possible water quality (without using a filter).

Pond Netting

For preventative maintenance, installing pond netting over your pond to help collect any debris before it reaches the water is an efficient approach to keep your water clean and to prevent material from adding to your pond’s sludge issue.

For more information, visit www.pondnetwork.com. These devices also lessen the amount of time you’d have to spend physically cleaning debris and decomposing sludge, which would otherwise be accomplished with a pond vacuum or telescoping net.

Pond Dye

It is possible to reduce the amount of UV light that enters your pond’s surface by using a pond dye, which will not only give it an attractive and bright color, but it will also help prevent algae and weed development in your pond by decreasing the amount of UV light that enters your pond’s surface. When algae and weeds begin to grow in the early spring, it is important to add pond dye.

Don’t Overfeed Fish

Overfeeding fish is simple to accomplish, and it is also one of the most significant contributors to excess nutrients in a fish-pond environment. Overfeeding is not only a waste of money, but it also has a negative impact on the water quality and oxygen levels in your aquarium. Make certain to only give your fish what they will consume. Remember that fish consume less food as the temperature of the pond lowers, and they may stop eating completely if the temperature falls below 40 degrees Fahrenheit.

The quality of the food you feed your fish is just as essential as the quantity of food you serve them.

Decide on a high-quality fish food such as Kaytee Koi Choice Premium Fish food to feed your koi.

Barley Straw

Another preventative approach to consider is the use of barley straw, which has been shown to help inhibit the formation of new algae in ponds. In other words, barley straw should aid in the prevention of planktonic algae growth, which will aid in the preservation of clean and clear water.

Another preventative option to consider is barley straw, which has been shown to help reduce the establishment of new algae in ponds. In other words, barley straw should aid in the prevention of planktonic algae growth, hence assisting in the preservation of clean and clear water.

How To Keep Pond Water Clean Without Filter

When you are not utilizing a filter, one of the most important things to remember is not to overload the pond with fish. This refers to the fact that you should avoid overcrowding the pond with too many fish. Fish consume a large amount of food and generate a large amount of waste. That garbage is an eyesore, it contaminates the water, and it has leaked toxic substances such as ammonia into the environment. There are fewer fish in the pond, which means there is less waste generated, and hence less of these compounds will be present in the water.

When you don’t use a filter, the volume of water in the pond has to be significantly more than the amount of fish in the pond when you do use a filter.

Because there is no practical method to filter these things out without the use of a decent filtration machine, it is vital to keep the fish population at a reasonable level. Featured image courtesy of Vital Safo/Shutterstock

2. Don’t Overfeed Your Fish

In the event that you do not have a filtration device in your pond, the next thing you should bear in mind is that you do not want to overfeed the fish at any time. The water will be contaminated if you overfeed your fish since there will be a large amount of uneaten food. Ammonia, nitrates, and nitrites are released by the uneaten food, as well as a variety of other chemicals. These compounds are toxic to fish, and they have the potential to induce algal blooms as well. This holds true for both the fish waste and the waste itself.

If you want to give your pond fish enough to ensure their survival, or a bit more, don’t overfeed them with a large variety of foods and treats that they won’t eat, or will consume too much of.

If you have a family of outdoor (or indoor) goldfish, or if you are thinking about getting one, we recommend that you read our best-selling book, The Truth About Goldfish, which is available on Amazon.

3. Engage In Regular Water Changes

In the event that you do not have a filtration device in your pond, the next thing you should keep in mind is that you do not want to overfeed the fish at any point. It is possible to overfeed your fish and end up with a large amount of undigested food in the water. Ammonia, nitrates, and nitrites are released by the uneaten food, as well as a variety of other chemicals. They are toxic to fish and may also create algal blooms, which is a problem in some areas. This is true for both the fish waste and the fish waste disposal process.

If you want to give your pond fish enough to ensure their survival, or a little more, don’t overfeed them with a variety of foods and goodies that they won’t eat, or that they will consume too much of.

If you have an outdoor (or indoor) goldfish family, or if you are thinking about getting one, we recommend that you read our best-selling book, The Truth About Goldfish, which is available on Amazon.com.

4. Clean Your Pond Regularly

The second method of keeping your pond water clean without the use of a filter is to physically clear it out. In this case, the most crucial part is to remove all types of solid fish waste, algae, uneaten food, decaying plants, and even dead fish from the water. All of these items decompose and emit harmful compounds into the environment, such as ammonia. Because you don’t have a filter, all of these things will simply accumulate. A wonderful strategy to keep these chemicals under control is to eliminate the factors that cause them to appear in the first place.

Additionally, you will most likely want to take decorations, plants, and ornaments from the water on a regular basis in order to clean them. The cleaner you keep your pond, the less likely it is that you will need to install a filtration system.

5. Use A UV Sterilizer

If you have a pond with no filter, a UV sterilizer will be a huge help when it comes to controlling algae. Because algae feed on a variety of pollutants that build up in the absence of a properly functioning mechanical, biological, and chemical filtering system, you will see algal blooms. Nonetheless, because algae require a large amount of sunlight in order to develop and spread, utilizing a UV sterilizer to neutralize the sunlight will go a long way toward keeping the pond water clear of algae.

6. Use A Nano Media Reactor

Although this is a little deceptive, it is not a filter in the true sense of the term. Nano-media reactors (also known as nano-filters) are similar to backup filtration units in that they specialize in the removal of organic pollutants such as nitrates and ammonia from water. While it is true that the device is in some ways a filter, which is why we called it “cheating,” in actuality, a filter and a nano media reactor are two very different things. If you have a large number of fish that create a lot of waste, a nano-media reactor is a fantastic addition to your facility.

Listed below are our top five recommendations.

Do You Really Need One?

7. Use Pond Dye

Okay, so applying pond dye isn’t exactly the most effective method of keeping your pond water clean, but it does have one significant advantage. Algae management is one of the advantages of this product. Because algae require sunshine to survive, preventing as much light as possible from reaching them will aid in controlling their growth (we have reviewed our top pond dyesover in this article). Because, as we have stated, algae smells. It’s filthy, it discolors the water, and it suffocates the pond’s occupants as well, so it’s crucial to keep this in mind at all times.

8. Have The Right Plants

In addition to keeping your pond clean, having the correct plants in your pond is useful. Submerged plants operate as natural filters, removing harmful compounds from the water as they filter it via their roots. The presence of a large number of submerged plants in your pond will aid in the absorption of waste products produced by the fish. At the same time, having some floating plants will aid in preventing some sunlight from reaching the water, so reducing algae development and increasing water clarity (we have covered our 10 favorite plant options herethat help to keep the water clean).

9. Take Advantage Of Cover

Being able to maintain your pond clean by using the appropriate plants is also important. In the water, submerged plants work as natural filters, drawing out harmful elements that would otherwise be present in it. It is important to have an adequate number of submerged plants in your pond to assist absorb the waste products produced by the fish.

A few floating plants will also aid in preventing some sunlight from reaching the water, which will assist to reduce algal development at the same time (we have covered our 10 favorite plant options herethat help to keep the water clean).

10. Use Special Additives

Adding special additions to your pond, mostly beneficial bacteria, is the last thing you can do to assist keep your pond water clean if you don’t have access to a filtration system. Beneficial bacteria will strive to break down ammonia and nitrates, decreasing the need for additional biological filtration in the process. If you do not have a filter and do not intend to get one, this is really one of the most effective methods of keeping your pond water pure.

Do I Need A Filter For My Pond?

It’s possible that you’re thinking, “Do ponds require filters?” In order to properly maintain your pond and keep the levels of ammonia and nitrates in check, you need install a filter in it. This is the most effective approach to guarantee that the water is properly oxygenated and that the pond remains clean. However, it is possible to maintain a healthy pond without the use of a filter, but with a greater degree of difficulty. If you have a rather big pond with only a few fish in it, the bioload may be low enough that you may get away with without using a filter altogether.

Also important is ensuring that your fish are not overfed, as this will reduce the amount of waste they produce.

Additionally, you may sometimes add some beneficial bacteria to the water, which will aid in the control of ammonia and nitrates.

Can Goldfish Survive In A Pond Without A Pump?

A pond without filters and pumps is extremely difficult to maintain, far more difficult than a pond with such features. However, it should be noted that goldfish may be able to thrive in pond water without the use of a pump, but there are a variety of things to consider as well as a variety of procedures you will need to do in order to make this happen.

  • If you have a large number of fish in your pond in comparison to the volume of water available, you may want a pump and filter to ensure that they have enough oxygen to thrive, as well as to offer appropriate filtration for the water. Depending on the overall bio load in the pond, this can be significant. The greater the number of plants in relation to the number of fish, the greater the quantity of filtration and oxygenation you will have. Plants do make a significant impact in this situation
  • If you keep your pond clean and well-maintained, your fish will be able to survive for quite some time without the need of a pump and filter, but when it comes down to it, you will run into serious difficulties sooner or later. It is preferable to have a pump

How To Get Crystal Clear Koi Pond Water?

For ponds with a large number of fish in comparison to the volume of water, a pump and filter may be required to ensure that the fish have enough oxygen to thrive while also providing appropriate filtration for the water. Depending on the overall bio load in the pond, this might be significant. Increased filtration and oxygenation are achieved by having a greater number of plants in contrast to the number of fish. In this case, plants are quite important. If you keep your pond clean and well-maintained, fish may generally survive for quite a long time without the need of a pump and filter.

To having a pump is preferable.

  • Keep the pond from becoming overly crowded with too many koi fish. The more the number of fish present, the greater the amount of waste they create, which necessitates the need for cleaning and upkeep. It is important not to overfeed the koi fish. Their use increases as does their waste production, and as a result, water quality deteriorates. Make an effort to have a large number of healthy pond plants in the pond, as they will assist in filtering the water. A good filtration system is one that can easily manage many times the quantity of water that is contained inside it every hour, and one that participates in all three primary forms of filtration to clear out as much trash and undesired elements from the pond. You may always include some helpful bacteria in the mix, as they will aid in the acceleration of the nitrogen cycle, the breakdown of waste, and the elimination of dangerous compounds such as nitrates and ammonia
  • However, this is not recommended. Not to mention that having a few snails in the pond is a good idea because snails make for fantastic cleanup crews

How To Clean Pond Water With Fish In It?

Although it is possible that you may need to remove the fish from your pond before cleaning the pond water, this is not always essential. Let’s take a brief look at a step-by-step procedure for cleaning pond water that has fish living in it.

  • Although it is possible that you may have to remove the fish from your pond before cleaning the pond water, this is not always essential. Consider the following short step-by-step procedure for cleaning pond water that contains fish.

We will now explain how to clear pond water without the use of a filter in this post, so please read on! Take advantage of the opportunity and get started right now.

Stop Over Feeding

Overfeeding can have a negative impact on the water quality of the pond. As a result, if you don’t want to use a filter but still want your pond water to be clean, you shouldn’t overfeed your fish in order to achieve this. You should determine the amount of food necessary for your fish based on the fish’s bodyweight and provide that meal once a day to the fish. When you overfeed your fish, the surplus food rots in the pond and degrades the water’s quality, thus you should avoid doing so. When you provide the necessary amount of food one time each day, the fish consume the naturally existing foods in the pond.

When they consume natural food, they contribute to the cleaning of the pond water to a certain extent. As a result, never overfeed your fish in order to maintain the pond water pure in the absence of a filter.

Make Use of the Pond Plants

It’s possible to utilize pond plants as a natural water filter when you don’t want to put in a mechanical or biological filter, which is something that many people are unaware of. Natural filtration is best accomplished through the use of floating pond plants. Their root structure has been created in such a manner that they are able to absorb various chemicals, heavy metals, and nitrate from the water they are growing in. These plants act as a natural filter for the water in your pond. They may also collect clay particles to their roots, which helps to keep pond water from becoming murky.

Consequently, you will notice less algae development in your pond as a result of this treatment.

According to pond experts, you should have creeping jenny, pickerel, horsetail, taro, cardinal, water lettuce, mosaic, blue iris, sweet flag, water lilies, and other aquatic plants in your water feature.

However, you must maintain a balance between the number of plants and the size of the pond.

Proper Cleaning and Maintenance

Make an effort to clean and maintain the pond in an appropriate manner so that you may enjoy clean and healthy water. If your pond does not have a filter, it is essential that it is cleaned on a regular basis. Get rid of any sludge and debris that has accumulated at the bottom of the pond. In rare circumstances, it may be necessary to drain the entire pond in order to clean it properly. If you don’t want to empty the water, you may use a pond vacuum or pumps to remove the debris from your pond instead of draining it.

Make Sure of Oxygenation and Aeration

Every fish species requires a specific quantity of oxygen dissolved in water in order to survive and thrive properly. It is impossible for fish to grow in water that has less oxygen. You will require a large quantity of oxygen to break down the waste items in the pond since you are not filtering out the waste materials. The biological oxygen demand, or BOD, is the amount of oxygen required by the body. Because the BOD load in unfiltered water is larger than in filtered water, you will need to aerate the pond with the assistance of pond aerators.

Add Beneficial Bacteria in Pond Water

Fish require a specific amount of oxygen dissolved in water to survive and thrive in their natural environment. Fish cannot survive in water that contains less oxygen. The waste items in the pond will not be broken down since you are not filtering them out, therefore a large amount of oxygen will be necessary. The biological oxygen demand, abbreviated as BOD, is the amount of oxygen required by the body.

pond aerators will be required since the BOD load in unfiltered water is greater than that in filtered water. Without the use of a filter, it will assist to maintain pure water by introducing oxygen into it.

Try Using UV Sterilizer

It is possible to use an ultraviolet sterilizer to battle algae in your pond when you do not have a filter system installed. Without a biological, mechanical, or chemical filter unit in place, the substances that are not being cleaned will increase the rate of algae development in the pond, causing the water to become cloudy. However, for algae to bloom, a certain quantity of sunshine will be required. The sterilizer, on the other hand, can be used to counteract the effects of the sun. It will prevent excessive algae development in the pond as a result of poor filtering and will help to maintain the water clean.

Try Using a Nano Media Reactor

It is possible to use an ultraviolet sterilizer to battle algae in your pond when you do not have filtration. Without a biological, mechanical, or chemical filter unit in place, the substances that are not being cleaned will increase the rate of algae development in the pond, causing the water to become green. Amount of sunshine required for algae to bloom is not known at this time. By using the sterilizer, you can counteract the effects of the sun. In the pond, it will prevent excessive algae development caused by insufficient filtration and will maintain the water clear.

Change The Water!

If your pond contains fish, frequent water changes are quite efficient in reducing the amount of nutrients and hazardous compounds that accumulate at the beginning of the pond’s life cycle. In the process of changing the water, you are effectively replacing 20 percent to 30 percent of the total amount of water available. It is advised that you utilize a pond calculator for this purpose. It is useful in calculating the volume of water in the pond. Draining the pond should be done with a pond pump.

Simply use it to water your plants or trees in your yard.

This can be accomplished by the use of pond dechlorinators.

You may get a variety of benefits by correctly changing the water, including lower nutrients, reduced hazardous compounds such as heavy metals, greater water clarity, less algae, and other advantages.

Use Barley Straw to Fight Algae

It is quite beneficial to do water changes in your pond if you have fish in it since it reduces the amount of nutrients and toxic elements that build up in your pond very quickly. In the process of changing the water, you are effectively replacing 20 percent to 30 percent of the total water volume. Using a pond calculator is highly suggested for this. Using it, you can figure out how much water is in your pond. Drain the pond with the use of a pond pump. The high concentration of nutrients in pond water allows it to be used as a natural plant fertilizer.

In the event that you utilize tap water for your pond, be certain that it has been dechlorinated before putting it to the pond because it may include a significant level of chlorine, which is lethal to fish.

They will aid in the removal of chlorine and chloramine from tap water, which are extremely poisonous and even lethal to the aquatic species in the pond.

Water quality improvements, such as decreased nutrients and dangerous compounds such as heavy metals, greater water clarity, less algae, and other advantages are possible when water is changed correctly.

Use of Pond Dye

If your pond contains fish, frequent water changes are quite efficient in reducing the amount of nutrients and toxic compounds that accumulate in the pond at the beginning of the season. When you change the water, you are effectively replenishing 20 percent to 30 percent of the total water volume. It is advised that you utilize a pond calculator to do this. It aids in the calculation of the pond’s water volume. Draining the pond should be accomplished with a pond pump. Because pond water has a high concentration of nutrients, it may be used as a natural fertilizer for plants.

If you want to utilize tap water for your pond, make sure you dechlorinate it first before adding it to the pond, since it may include a significant quantity of chlorine, which is lethal to the fish if not treated properly.

They will aid in the removal of chlorine and chloramine from tap water, which are very poisonous and even lethal to the aquatic life in the pond.

Is It Possible to Keep the Pond water clear without a Filter?

In order to get the answer, numerous factors must be considered, including the species of fish you wish to keep, as well as the size of your pond and total biological load on the pond. In general, the necessity for a filtration unit increases in direct proportion to the amount of biological load present in the pond environment. The fishes that live in ponds with fish produce the greatest amount of bio waste. Having a well-functioning filtration machine is essential when the biological load is large and it is difficult to maintain the balance on your own.

The presence of a high concentration of helpful bacteria in the filter box will assist you in overcoming this issue.

The natural progression of this style of pond is that it becomes easier to maintain.

Final Thought

Maintaining the clarity of the pond water without the use of a filter might be difficult for you. However, if you follow these suggestions, I believe you will be able to maintain the water pure without the need of a filter. A healthy ecosystem in your pond may be maintained by keeping fewer fish, adding some pond plants, and routinely aerating the water in your pond. I hope you found these suggestions useful.
