UV Filters for Koi Fish Ponds

UV filters for Koi fish ponds are one of the vital components in your pond filter system. Consequently, we can recommend the right UV clarifier for your needs and supply those made of Stainless Steel 304 Grade.

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

We offer affordable stainless steel UV filters that are durable and dependable, unlike those made of plastic. We can custom-manufacture UV filters according to your water flow needs. Consequently, our smallest systems can handle a 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.

Cost of UV Filters

The cost of UV filters for Koi fish ponds starts from Rs 10,500 onwards. Consequently, 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 UV pond filters UV sterilizers Or UV clarifiers. 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. 

How to Choose the Right System

When planning to buy a 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. Remember to note the temperature of the inlet and outlet water, as it can impact the water’s ecology. Consequently, fish 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. Make sure that the rated flow rate of the UV system matches the maximum rated pressure of the selected Pump.
  5. Specifications for inlet and outlet plumbing connections.
