Pond UV Filter



You might see your fish pond water crystal clear! But is the water quality good for the fish? Not necessary always. You must be aware of functions of a Bio filter! Bio filters helps break down ammonia very fast and dead algae. Along with bio filter, you should always use a UV filter. In the Indian conditions specifically, water parameters are very poor.



What is a UV Filter?

UV filters comes in different sizes and shapes apart from functional capabilities. UV Filters are used in even purifying drinking water. Fish pond UV Filters have basically 4 components. A Power Ballast : This supplies constant and correct power to the UV bulbs

A Plastic or Steel Case: The case allows free flow of water in and out. These are air tight case thru which water flows. Stainless steel Body is recommended in case you can afford. The price may be multifold, but the effectiveness also increases. Because the UV bulb inside when is switched on, reflects on the Steel and thus impacts flowing water more

A quart sleeve: this sleeve is a protective water proof chamber for the UV bulb.

UV bulb: So the UV bulb goes inside the quartz sleeve. And when powered ON, emits a blue light. Large size UV filters come with more than 1 UV bulb also.



These days UV come with a little more intelligence. They can be auto programmed or can be controlled remotely.





Does UV help in removing the algae in an already infected tank?

UV light is not a chemical to treat the water. They do not help in removing the algae. Basically you should start using the UV on the day 1 when you start the pond and if not, you need to thoroughly clean the pond before using the UV. UV will essentially help in keeping the algae in control. It does not treat the water like a Algae remover chemical.



How to select the right UV:

Our recommendation is that for every 150 – 175 L of pond water you need a UV of 1W, which essentially means that a pond of 7000 – 7500 L, you need a 25W UV minimum. In case if the pond is outdoor, you can also use a 50 UV for a 7500L pond.

The chances of algae attack will be low if the pond is indoor, and increases if the pond has direct sunlight.



Care your UVs

You should take utmost care while using a UV filter.

Always ensure that the UV is connected to running water when switched ON. Otherwise you will land up, burning the UV< bulb, the quartz Sleeve or even the plastic body or the ballast.



Please change the UV bulb every 18months or even before for best results.

Keep on checking if your UV filter emits blue light

Please open and clean the UV Sleeve occasionally. The sleeve might be dirty with the fish waste. And needs to be cleaned periodically. If your pond bio filter is functional, then this issue should be less. If there is lot of dirt in the quartz sleeve, you can be sure that the Pond bio filter is not functional



Use the right flow rate of the pump. Every UV filter comes with a flow rate recommended. If you use a filter with low flow rate then the filtration process will take longer time and if you use higher flow rate then either the water will just flush thru or even damage the Plastic body of the UV filter due to excessive pressure.





Please note that UV filter is not a replacement for Bio filter. UV filter doesn’t help in keeping the water conditions apt for fish. These are only to compliment the functioning of bio filters and will clarify the water to look crystal clear.
