Koi Pond FilterKoi Pond Filters serve two purposes. It serves as a mechanical filter (removing dirt from the pond) and serves as a biological filter (providing the proper environment for the development of nitrifying bacteria). A Koi Pond filter is the most important piece of pond equipment you will need for your water garden and backyard Koi ponds. If you are planning to have even the first Koi fish, do NOT treat this piece of pond equipment as an option. Pond fish are just like any other animal in that they excrete waste that would be toxic if it accumulated in their bodies. Fish are threatened if they are exposed to a buildup of toxic waste. A pond water garden or a Koi pond is a completely enclosed water body that must deal with an abnormally high biological load. You will need to be aware of how to provide good water quality in an artificial pond. Fish are not able to escape from poor water quality. Your fish will be stressed and it will make them more susceptible to disease. Which is preceded by a tell tale change in behavior. Why do I need a Koi pond filter? A Koi pond filter reduces the amount of ammonia in your backyard Koi ponds. You know (hopefully) that ammonia is the main cause of Fish death. Ammonia is a toxin and high levels can burn the gills, the skin, the gut and cause death.

Basic Principles Of A Koi Pond Filter1. All the water should pass through the filter system. Any water by-passing the filter will dilute the effect and efficiency of the filter system. 2. The entire pond volume should pass through the filter system as quickly as is practical and returned to the fish, i.e. the turn-over rate of the pond volume should be high. 3. Once in the mechanical or settlement part of the filter, the water should slow down. Slow moving water encourages settlement. Flow rates of the entire system must be maintained. Increasing or decreasing the size of the filter chambers can adjust the slowing down or speeding up of the water flow in the filter system. 4. In the bioconverter part of the system, the water can flow fairly quickly as the conversion of ammonia to nitrite to nitrate takes place immediately on contact with the nitrifying bacteria. The flow rate must not be too quick or the water may flush the heterotrophic bacteria from the media.
Building a EcosystemRemember you are building an ecosystem not just a pond. Buying the cheapest filter on the market leads to regrets down the road. If you don't have a pond filtration unit you will be setting your fish up for failure. In order for a pond filtration unit to be effective it must run 24 hours a day. The constantly fresh supply of oxygenated water is what keeps the filters bacteria thriving. A natural water body keeps clean by the constant flow of fresh water through it. In a pond water garden, a filter is required to keep the recirculating water clean and healthy for your fish, if they are deprived of this for even a couple of hours then they will start to die and the pond filter will lose its effectiveness. Biological FilterUnlike a swimming pool filter, which is to keep the water clear and clean, it is the chlorine added to the swimming pool which keeps the algae from growing on the sides of the pool and is really responsible for the clear water. In a Koi pond, we cannot use chlorine and we want the fine velvet coating of algae to grow on the sides of the pond. In fact, if algae does not grow on the pond sides then there is a major water quality problem. Your Koi nibble on this algae, providing nutrients, giving them their luster and color. We also want the water to be clear so that we can always see our Koi. Therefore something other than chlorine must be used to keep out the unicellular algae (causes pea-soup water) and the long stringy algae. These are the purposes of the Biological Filter. Likewise, just because the water is clear does not mean that it is healthy for the Koi. In fact, the ideal water is clear with a slight greenish tint, as well as being odorless and tasteless. A filter must be broken in gently over the first few months of its life. To get a filter ready for your fish it must be broken in. A vital part of filtration is living, unlike mechanical filtration, the bacterial colony takes time to become established. The steady turnover of water through the filter provides the bacteria with a constant source of “food” in the form of ammonia, as well as an essential supply of dissolved oxygen. Add a few fish at a time, so that the bacteria can adjust and catch up with the rate of ammonia being produced by the fish.

How does your water become toxic?Your Koi produce wastes: Ammonia from their urine, which diffuses, yet the water remains clear and it becomes toxic to the Koi as it builds up solid wastes which also add more ammonia, plus toxic hydrogen sulfide, methane gas, etc. and it clouds up the water. Other debris. as dirt,leaves, and uneaten food adds to the accumulation of toxins to the water quality. Koi Pond Filters contain a biological material for aerobic bacteria to grow upon. These bacteria metabolize and rid the pond of the ammonia and wastes. Such a biological material in the 1980s would have been pea gravel or volcanic rock. Nowadays, however, many synthetic materials are being used (brushes, foam, or mattresses). The major requirement being that it contain the most surface area to house the maximum amount of good bacteria (aerobic). ![]() This E-course Goes Into Specific Detail on Ways to Keep Your Koi Healthy and Keeping Your Pond In Optimal Condition To Support your Koi
