What size UV?

[Gags]

My pond is a wildlife pond , it's around 12000 litres...what size UV would I need just for algae control not sterilisation...?

I have a wildlife pond with biofilter installed and want to enjoy the wildlife...I have hundreds of newts and fear I'll get green water as my plants are not established yet as I built the pond last October so it's only 7 months old...

Based on my limited research you should be okay with an 18-watt UV for your sized pond. I have a 450+ gallon above ground pond and my 9-watt UV is rated for 1800 gallons. The only reason I went with that one as opposed to the smaller one that is rated for 660 gallons is because the smaller one wouldn't have worked well with my 1000 gph pump.

What ever you decide to do just make sure your UV filter is compatible with your current pump configuration or better yet just put the UV filter on it's own pump/circuit separate from your other filtration.

Ok thanks for the info friend

Is there any benefits to keep it running if water is already clear?

If you are going for a wildlife pond, why run a Uv? You are establishing the base of the food chain with new pond syndrome ie green water and the zooplankton that feeds on it. Running a Uv circumvents this. The green water will disappear naturally and once your plants are established will most likely not return at all if the pond is set up properly ie enough plants and proper circulation.

Also, Gags you will get more attention to your post if you create a new one rather than piggyback onto a 5 year old one.
