Fish Pond Filter / Koi Pond Filters


Filtration is a key process in fish keeping be it a Bowl / Glass Tank or Outdoor pond or pool. Fish will have a healthy life only in clean and aerated water. In the natural environment like River and lakes, the water is renewed automatically. The Nature does the water cycle by itself. Yes of course humans pollute it most often.
 We will talk about aeration in the a different thread. For now let’s stick to Filtration. Biological filtration is the best suited method for fish ponds. In a captive fish pond the ecosystem is closed and hence the water cycle will not happen by itself. Any kind of impurity generated inside or induced from outside needs to be cleared by force.
So there are two parts of clearing these impurities.
  • Have a good Filter system
  • Partial or full Water change (Need based)
Selecting a Filter System
There is a myth that green water in the pond is not good. Or the Black bottom of the pond means its water is not good. Reality is that some algae in pond is necessary and crystal clear water also doesn’t mean its good. The impurity which is fatal for the fish is ammonia which is not visible by naked eyes and needs testing kits and tools.
How does a biological Filter work
The Basic function of the pond filter is to break down harmful ammonia into Nitrates. This is done by essential Bacteria. Re-circulating water of the pond thru the filter with essential bacteria is the only way to do so. Essential Bacteria is colinised in the filter media inside the Pond filter. These essential bacteria needs to be recharged periodically based on the need. There are many brands which produce the essential bacteria which comes in Liquid and powder form.
Sunsun and Boyu are world famous brands of Pond filter manufacturers. The pond filters come in different size.
While choosing the right model, please ensure that the filter has double the holding capacity of the pond and the pump has half the capacity of the filter. Which means the pond filter should not pull and flush the water in the same flow. The water taken from the pond needs to mix with the filter media and  enough essential bacteria should be mixed in the water.
Some of the popular models of Pond filter are SunSun Grech CPF 15000, BOYU Gardening Pond Filter EFU 15000A, Sunsun CUF 5011, Boyu Gardening Pond Filter EFU 10000, SunSun Bio Pond Filter CBF 200T, Boyu Garden Pond Filter YT 6000, SunSun CPF 30000 Pressure Pond Filter, Sunsun CPF 50000 Pond, Boyu Garden Pond Filter YT 25000

Fish Pond Air Compressor

Everything about Pond Aeration Everyone knows that pond with fish needs good amount of Oxygen. Life without oxygen is impossible and a pond with less amount of Oxygen can hold only less number of fish. To support large amount of fish in a captive pond, you need to provide external Air (which will contain Oxygen). Pond with fish will generate a huge amount of toxic air from the waste and decomposed material at the bottom and hence the bottom of the pond will always lack Oxygen. A lot of people use spray bars or fountains to re-circulate water thru fresh air by means if which Oxygen is added to the water. This was harmful gases will be released to the atmosphere and Oxygen gets added because the surface area of water getting in contact on the moving water will increase. Its always advisable to leave the surface (top) of the pond free from Water lilies and lotus plants because these plants cover the top, the maximum area will not have access to fresh air. Otherwise you need to have H

Aquarium Chiller

Fish and invertebrates  are cold blooded and hence you must be aware that their body temperature is controlled by the temperature of the habitat they live in. Water temperature in fish tank or Aquarium hence is a very important factor. Sudden fall or rise of even 5 degree temperature will become fatal for the fish. Hence its recommended to keep the water temperature stable. The fish requires optimal temperature range and not extreme. In India, certain regions are prone to extreme climate. The variance between day time temperature and night temperature varies from 5 degrees to 25 degrees. These can cause same change in water in a pond or fish tank. In such conditions we recommend use of heaters and chillers / aquarium fans. Continues cycles of temperature variance in water can cause stress to the fish and stress can cause various disease because during high stress the immune system doesn’t work properly. More over increase in water temperature also decreases the Oxygen le

Fish Net

This article is not for medium and expert level aquarists . But may be beneficial for entry level hobbyists. There are some basics to start a new aquarium. And a lot of people are ignorant towards and get into trouble or find difficulty after they start off.This is a basic requirement of fish keeping. Irrespective of what ever level of expertise you have, fish net is a must. Fish is very sensitive in nature. Handling without care will not only physically harm them, but also physiologically. A scared fish can move around very fast and can hit the equipments and wall of the tank and harm themselves. More over a stressed fish will have shorter live.  Fish nets are available in different sizes and hence choose the right size of the net based on the size of the fish and the tank.  Fish net will come handy while cleaning the tank or changing tanks or during transport.
