Water clarity can be improved by adding more pond plants, cleaning out excess sludge, installing pond netting, repairing leaks, and adding extra beneficial bacteria. I hope it helps! Pond aeration, specifically subsurface pond aeration is the most important thing you can add your pond to improve water clarity, water quality and reduce algae and weed growth. This article was so helpful! What kind of fish are you looking to keep? If your pond has fish in them, water changes are very effective to reduce the nutrients and harmful substances that grow up very first in the pond. On the other hand in a pond with a small population of fishes in them, the bioload will not be that much high. If your water quality test results are showing low ammonia and healthy parameters, more plants likely would not help much and would be more a personal choice. I know you mentioned that you don’t have electrical capabilities where the pond is located, but there are some battery operated pumps as well as heaters available that will help to keep the water continually mixed and at a livable temperature. If I was in your situation, and building on the above advice, I’d firstly take a broad range water quality test and take note of readings for ammonia, nitrites, nitrates, pH and KH (alkalinity). Do keep me updated on the pond situation if anything happens in future! A large duck pond is easier to clean than a small duck pond because a large pond develops its own ecological system to filter out bacteria and keep the water clean. Could I switch the filter off between October & April if I add in bacteria when I re-start it? In terms of your pump and filtration system, I wouldn’t leave it like that for more than a day or two as dissolved oxygen levels can deplete very quickly, particularly with your fish spawning and many babies being present. As well as this, water from our mains supply has high levels of both chlorine and chloramine – both of which are highly toxic to aquatic life. Obviously plants, wildlife and fish all require some muck to survive, but simply cleaning a small area around the filter and pump may be all that’s needed to prevent major clogging. These tips are part of a series on Backyard Pond … The fish have been in good health apart from about 2 to 3 years ago when rudd started dying: I then had it drained and we scooped out a lot of sludge and started again, and then 3 months ago had a big clean up removing much sludge and lots of hornwort (without draining it fully) and put in the filter, since when the water clarity has improved from completely murky to very clear. I don’t know the volume of the hot tub, but it looks like it seats eight people. Stop Over Feeding. For other fishes, experts recommend that you don’t stock more than half of an inch of fish per 10 gallons of water. Pond plants will ensure that excess nutrients and harmful substances are absorbed, whilst also working to keep away nuisance algae and weeds. In some cases, you may have to drain the total water of the pond to clean it. It is rain-fed only (no filter nor spring).The goldfish reproduced this summer and there are a few little ones in the mix now. How To Install A Bottom Filter In Your Pond?

My only advice would be to also consider a concrete sealer, such as “G4 Pond Sealer”, which will provide a protective outer layer to prevent potential leeching or deterioration. Adding aeration in the form of a solar aerator, electric aerator, or even fountain display, will help improve oxygen content and surface movement. It’s always very interesting to hear from someone with a much larger pond and less common fish species. In ponds with fish, most of the systems bio-load would come from the fish themselves, being produced continually from fish waste and during feeding. The best time to clean a pond of sludge is the end of autumn in preparation for winter where ponds freeze over, as this is when fish are most vulnerable. Your email address will not be published. Bay 2: Blue matting – This is an excellent filter media as it has a large surface area giving it an excellent bio-mass retention. That filter is a great model! You should calculate the amount of food required for your fish according to the bodyweight of fish and supply that food once daily. I’m very glad to hear the site has been helpful to you! Is there anything else I should add to keep the fish alive during the winter? We only recommend this 1-2 times a year, with the best times being early spring and early autumn where debris starts to build again. Huge Thank You again, I will be back to you with the water test results. For lightly stocked ponds with small fish, they’re an interesting alternative to normal filtration that can help with water quality and provide a more natural feel to the pond. ‘Dirty’ water doesn’t always mean unhealthy water, and many wildlife ponds I’ve worked on have been very mucky but still have had good general water quality. Let me know if you have any more questions, and sorry again for the delay. Should I remove the surface plants once they begin to die after the frost? Also we’ve only ever filled it back up with rain water from our water butts is this ok? You can find a more complete list with fish that actively eat larvae and their benefits/drawbacks for different kinds of ponds here – https://pondinformer.com/pond-fish-that-eat-mosquito-larvae/, This article is very helpful for a part of our Thesis. Overfeeding can adversely affect the pond water quality. Beneficial bacteria which are at the heart of a ponds biological filtration system require large amounts of oxygen to function efficiently. Does concrete work for this? I dont plan on keeping fish but would like to make it less deep. My work has been keeping me very busy these past few weeks. It has no filter but receives rainwater, diverted from a wooden barrel roof collecting system. All thanks to you. Calcium carbonate and magnesium carbonate make up the largest (and most important) buffer in fresh water eco-systems, but these are mostly found in hard (limestone) mains water or through manual supplementation. As pond water has a high level of nutrients, you can use it as a natural fertilizer for plants. Your pond sounds very established and healthy, so you’ll have a huge abundance of natural bacteria present and ready to take over the filter media again. I net it from autumn to spring but the plants/fish create plenty of sediment, water used to be very unclear. Which of those fishes can be together in that particular pond? It will induce oxygen in the water and help to keep the water clean without requiring a filter. For this reason, try to have the right amount of plants is one of the simplest natural ways of having clear water in the pond. It is 2 feet deep. If you are changing the water properly, you can have many benefits like reduced nutrients, reduced harmful substances like heavy metals, improved water clarity, fewer algae, etc. Also we have 1 goldfish with fungal infection what is the best stuff to get? To help make this possible, we have put a list of some tips and techniques to keep your pond clear and clean without a filter. Even without a filter in the pond you can still boost the efficiency of your beneficial bacteria by providing plenty of oxygen, aeration, and keeping on top of waste levels. Bacteria will require a bit of waste to stay alive (it’s what they use for nutrients), so making a pond completely sterile is bad for biological filtration. Bay 3: Three layers of reticulated foam with different density of porosity of each layer. However, my long-term concern here would be the potential for high pH swings in the absence of carbonates. Oxygenating pond plants offer shade as well as reduce algae growth. However, with lighter stocking densities or in fish free ponds the KF18,000 will comfortably cope with much larger volumes. The algae is a recent thing really and is taking up about a quarter of the pond. You can do that by making sure your water has plenty of beneficial bacteria. Even without a filter for a few months, I think your water quality would likely hold strong, and you may not even see a drop in water clarity until Spring when temperatures begin to rise and wildlife and fish become more active. 1) This may actually increase gunk over time, as the lilies roots will be removing a large quantity of excess nutrients/waste particles, but whether potted or not, they’ll still drop foliage into the water contributing to overall gunk. Including a few links below for further reading and to answer some of your other questions: https://pondinformer.com/best-pond-heater-de-icer/ https://pondinformer.com/best-koi-pond-aerator-system/ https://pondinformer.com/best-pond-vacuum-cleaner/ https://pondinformer.com/how-to-keep-pond-fish-alive-winter/ https://pondinformer.com/best-beneficial-bacteria-ponds/. Well, using this may well be referred to as cheating. in your pond. I plan to convert an unused hot tub into a pond/water garden, relying largely on aquatic plants to keep the ecosystem healthy. If you have a small amount of fish in your filterless pond, you’ll need to clean out more sludge more regularly if you want to keep water quality good. Many of these problems cannot be removed with regular filters even if you tried, but can be prevented with a solid cleaning routine and daily upkeep. Thanks again Chris – you are a Star! So in this article, we will be discussing how to clear pond water without a filter. Benefits: Controls algae growth, adds more oxygen content, and helps remove excess nutrients from water. Have done the tests with the NTLabs kit (another Thank You – a really neat product!) As well as this, algae can quickly overtake a stagnant pond and mosquitoes love laying their eggs in slow moving water – both of which you should try to avoid to you want a clean pond. If you don’t like the idea of a regular filter in your pond, but still want to improve water quality and clarity, you could consider opting for a bog filter instead. The main reason why you may have been recommended to leave your filter on in winter isn’t so much for waste compounds, but for aeration and oxygen. Because in this period algae and weeds start to bloom. How much of your pond has algae would you say, and has it always been there? ), and inside are 5 adult goldfish and a myriad of frogs, newts and an occasional turtle. thank you in advance for your input! How To Build An Indoor Fish Pond – A DIY Guide, Tractor Tire Pond – How To Build, Decorate & Maintain. I acquired a pond (approx. When you don’t have a filtration unit in your pond a UV sterilizer can fight against the algae for you. As well as aeration, topping up your ponds beneficial bacteria populations with a concentrated bacteria supplement will help keep levels high and reduce overall waste. To look after them I rinse the filter in fresh water once a month. A final thing you can do is make sure you have plenty of water flow and aeration, which can be from a waterfall, fountain, or pump system. Thank you very much! For this, you can refer it also as a filter that’s why firstly I said that it is kind of cheating. Pond water that's turned green in color can make your pond look very unattractive.

Let me know if you have any other questions. Green water is caused by algae, and there are a number of simple ways you can tackle the problem. The answer would depend on various facts like types of fish you want to have, the size of the pond and the overall biological load on the pond. It helps to calculate the water volume of the pond. Particularly in Pennsylvania with so much vegetation about (it’s a gorgeous state, but certainly lots of leaves!). If results are still good, I don’t think you’ll have any issues for the rest of the season and can simply wait until spring to turn it back on. As well as this, making sure your beneficial bacteria populations are healthy will help keep sludge in balance, and topping up with natural sludge eating bacteria can help boost your bacteria’s efficiency. Water changes will usually be around 10-30% of water by volume, and can be performed by draining the top levels of water using a pump, vacuum, or siphon hose into the garden. But if you follow these tips I hope you can manage to keep the water clear without using a filter. As BOD load in higher in unfiltered water, you will need to aerate the pond with the help of pond aerators. It can be quite difficult to maintain a healthy pond without any aid from filters or pumps, so kudos to you! The only time we’d suggest keeping fish in a pond without a filter is with lightly stocked goldfish in a heavily planted pond with regular maintenance. The choice of whether or not to have a filter in your pond would depend on the fish you keep, the size of pond, and the overall biological load (waste levels) present. In ponds without fish, a small amount of sludge is actually beneficial, as it provides bacteria it’s energy resource, plants their nutrients, and wildlife, such as newts, a place to hide! You are practically replacing 20%-30% of the water volume in the process of changing the water. Eco Filtration – Are Bog Filters (Plant Filters) Worth it? The presence of a fungal infection tells me that you likely need to monitor your water quality more closely, and I would urge you to perform weekly water changes of 15-25% to maintain healthy water quality, particularly since the pond gets cleaned once per year. It also indicates that the levels of muck/gunk are not so high that they’re causing major issues, so the decision on whether to lower them would be another of personal preference. I would be grateful for any assistance. Best of luck with the new pond! Since the largest majority of sludge is on the pond liner, the easiest way to clean it out is with a basic pond net or a more heavy duty water vacuum. A green pond can quickly turn into a clear, clean, healthy body of water that can be enjoyed for years to come. Many thanks in anticipation.Diane. If you don’t have any plants in the pond you’ll have to carry out far more maintenance to maintain good water quality and clarity without a filter. Organic debris which falls into a pond will eventually decompose  as sludge and leak color, called “tannin“, which will make your pond a yellow brown color. If water quality is good, I don’t think adding more fish will be a problem so long as you remember to test regularly to ensure the pond isn’t becoming overstocked. Thanks again! Once this is done shall i still treat the water for the fungal problem? 2) Although this wouldn’t remove the gunk itself, it would probably prevent some muck being kicked up and making it’s way into your filter system. I don’t fancy doing that throughout the winter but am told the filter should run 24/7/365. For prevention, we recommend installing a high quality pond net which will help catch fallen leaves and twigs before they can sink in the pond and contribute to sludge. Can you recommend a water testing kit suitable for this pond? Barley straw will gradually decompose and fight the algae problem. Although it is tricky to have clear water without a filter in a pond but not impossible. Drain it, clean it, and cover it for the season. Plants not only provide protection areas for fish but hinder the growth of algae by reducing the amount of sunlight in the pond and utilizing the nutrients algae need. THANK YOU! Privacy Policy | Cookie Policy | Contact | About, How to Keep a Pond Clean Without a Filter System (updated 2021 guide), 5) Perform Water Changes (If you have fish). Ah, sorry again!

Bay 4: Six way foam block manifold assembly on top of six cubic foot of Flocor. 5.I have been cleaning the filter completely until water runs clear through it (tap water) – should I not clean it so thoroughly but leave some gunk in it? However, you can skim it out with a net like you mentioned as well! Get Rid of Debris Decomposing natural compounds will feed the string algae and allow the water to become murkier than it already is. Therefore, when you don’t want to install a filter you have to keep the number of fish equal or bellow the recommended number. Therefore, when you don’t want to use a filter, yet want your pond water to be clean, you shouldn’t overfeed your fish. Even if your water quality is good, and your fish seem healthy, the problem with ponds is they can be subject to sudden changes in quality, which can negatively impact fish. But algae will require an amount of sunlight for blooming. Flow will stop insects laying eggs in the water, which will contribute to waste, and will also provide more oxygen for beneficial bacteria to break down waste. 7. Just be sure to wait until the sealer is 100% dry before adding water, as most are toxic in liquid form to both plants and fish. The debris stays in this basket instead of clumping up the drain. The large surface area of Flocor tubes makes it an ideal filter media. Lots of marginal plants, and water lillies covering about 30% surface which are mainly free-rooted. This oxygen is called the biological oxygen demand of BOD. When the biological load is high, it becomes hard to maintain the balance without a well-functioning filtration unit. A proper balance between fish and aquatic plants will help keep pond water clear. As you don’t have a filtration unit in the pond. Water quality is less of a concern in winter as fish produce less waste, they browse much less, and decomposition of organic material slows. To treat the goldfish, you can quarantine the one for treatment that has visible symptoms, and treat with a salt bath, potassium permanganate, acriflavine, and several other products as gone over in detail in this article: https://pondinformer.com/koi-fungus-treatment/. Hi I dont know if anyone else does this but we have an outside pond no pump no filter but we have goldfish in there and we don’t feed them but they have always lived. I hope that helps.

Although many of you don’t know this, you can use pond plants as a natural filter for your pond water when you don’t want to install any mechanical or biological filter. As you are not filtering out the waste materials in the pond a huge amount of oxygen will be required to break them down. How To Keep Pond Water Clear Naturally. 6) If your water quality test results are showing normal/low ammonia and other waste compounds, there is likely no need! In biological filters, bacteria grow on the surface of filter media to breakdown harmful elements. I’ve never checked the water quality but it looks quite clear, it doesn’t smell at all, and the fish are fat and seem happy. The more surfaces there are to support microbes, the cleaner the water will be. Moreover, these pond plants give shade which results in fewer algae growth due to lack of sunlight. Utilize A UV Sterilizer I don’t have electrical capability where the pond is located. Just like a filter box which has a higher amount of beneficial bacteria, a bog filter works the same as regular plants, although the higher concentration of plants and optimized water flow makes for better overall filtration. Fish will instinctively be attracted to areas of higher oxygen and better water quality anyway, so they’d likely congregate around the smaller aerators if they ever needed to. The more oxygen you can provide to your waters, the happier they’ll be in the environment. So – do you think I’m OK to turn filter Off October-April? This way they work as a natural filter in your pond. It will stop the excess growth of algae due to improper filtration and keep the water clean in the pond. In the ponds with fish, the maximum level of bio wastage comes from theses fishes. 3) This would almost definitely result in more muck/gunk being lifted from the pond floor and the filters clogging even faster! For example, if you have a excess nutrients in the water making it cloudy, a water change may help temporarily, but the water will eventually return cloudy unless the source of the nutrients is reduced (i.e., excess sludge). Without a pump powering a filter system, you likely won’t have much aeration, and this can be hugely problematic for both wildlife and fish. A thin layer of slime is fine, but in my opinion, it’s often better to clean a little too much than too little, as bacteria will re-colonise clean media extremely quickly in a established pond, but will struggle if the surface is covered in gunk. Your site is very interesting and informative. Given that I’ve cleaned it thoroughly with tap water for a couple of months now should I introduce some bacteria (into pond or into filter)?

Grow water lilies over 70% of your pond’s surface and watch as the algae magically disappears over time. If you use barley straw in liquid form, just simply add the required amount of it with pond water. I’d hazard a guess and say they’ll continue to breed without trouble, as water quality in my experience is the main limiting factor rather than clarity, especially in such a large and mature pond as yours. In stagnant ponds with little flow aerobic (oxygen using) bacteria will die and anaerobic (carbon dioxide using) bacteria will begin to thrive. Their root system is developed in such a way that they can take our different chemicals, heavy metals, nitrate from water. In addition, whether or not your fish can survive outdoors for the winter depends on their species. Alternatively, you could try installing a regular skimmer system to catch floating debris before it sinks, or check into a floating lake skimmer system designed for water bodies with changing annual water levels. Answered both your posts in the previous comment. If you don’t want to drain the water using a pond vacuum or pumps to remove them from your pond. The overflow goes downhill to a river at the bottom of the garden. If so, were the fish happy and healthy? However, when a ponds waste levels exceed the ponds biological filtration capacity, the eco-system will begin to suffer as oxygen content lowers and water quality degrades. This site uses Akismet to reduce spam. For larger models, you’d need to contact specialist retailers as they’re not so readily accessible in the UK. However, your pond is quite large, and a single carp is unlikely to be the main cause here. Since doing this, I’ve been able to avoid algae growth in my ponds, and keep the water clear.

Therefore, if you want to keep your pond water clear without filter, don’t overpopulate your pond and stock the recommended number of fish. Here’s how it works: Single-cell algae thrive on nitrites, a byproduct of ammonia breaking down in the pond. Though the article mentions koi, many of these fungal ailments affect goldfish as well, and the treatment options will work just the same. You can use pond dechlorinators for this purpose. It also has a hole in it about 1 inch wide.. used previously for a hose/pump. Every fish species requires a certain amount of oxygen dissolved in water for living comfortably. Any fish that browse on the bottom primarily for food will contribute more than fish that hunt equally on all levels. Less number of fish means less waste. 7. Hi Chris – that is fantastically helpful, Thank You! And do you know of/have views on the ‘PondHero Sludge Muncher 1400W’ one? It will take some time but surely work. Running a pump/filter is often the easiest way to counter this, but you can also do it in other ways, such as with de-icers and aerators.

This is on top of a layer of approximately 2 cubic foot of flocor. Historically both rudd & tench have bred in it – I worry now that it is so clean and clear will this hinder the fish breeding (they must feel very exposed now!)? For ponds with lots of goldfish, or larger koi, a filter system is almost always needed to keep up with the biological load fish produce. Back to me: re pond vacuums – do you know if Matala are available in the UK (nothing shows up on google)? Stocking guidelines may differ slightly per individual species. It is very effective when you want to control algae growth. Examples below: https://www.fishkit.co.uk/diffused-air-aeration.html https://www.heathlandaquaticengineering.co.uk/lakes/lake-aeration/diffused-lake-aeration/aquaair-diffused-lake-aerator/. If they’re only slightly worse, perform another test in a week or two to see if they’re holding.
