UV Filters for Koi Fish Ponds

UV Filters for Koi Fish Ponds

UV water filters are one of the vital components in your pond filter system. We can recommend the right UV Clarifier for your needs, and supply with the ones which are made out of Stainless Steel 304 Grade.

If used correctly it can help to keep your pond clear and free of algae. The right intensity and correct flow rate through the UV water clarifier will ensure algae-free water.

Unlike the ones made out of plastic, we can supply you with sturdy and realisable UV Filters which are made out of stainless steel at a reasonable cost. The Uv Filters can be custom manufactured as per your water flow needs, out smallest systems can handle a water flow of 250 Litres per minute. We can design, configure, and manufacture systems which can handle more than 33,000 litres of water per minute.

The cost of UV clarifier's starts from Rs 6500 onwards and the delivery time is anywhere between 5 to 6 weeks for bigger systems and 4 to 5 days for smaller systems.

Uv water clarifiers are often called a UV pond filter or UV sterilizers Or UV clarifier. But the function of a UV filter is not to filter water but it helps to keep a tab on the growth of algae and restricts the growth of other microorganisms.

As discussed earlier the right intensity will help in maintaining a good biological environment. 


When planning to buy UV filter the following points are to be noted.

  1. Whether it is of the right intensity, and the wavelength of the Uv Lamp is correct.

  2. Make a note of the inlet and the output temperature of the water, since it will affect the ecology of water. Fishes like Koi are extremely sensitive to temperature changes.

  3. Check the IP Classification of the Uv System. I.e whether it can be installed exposed to sunlight and weather.

  4. Check for the maximum rated pressure, I.e the rated flow rate of the UV system should match with that of the selected Pump.

  5. Inlet and outlet plumbing connection specifications.

Following are the details of standard models available with us, kindly contact us for price details.

Any other configuration which is not listed below can also be custom manufactured upon request.
