The size of the uv is best determined by the water flow from your pumps.
Aquatic Eco catalog has a lot of good info on sizing. If your pump is too
strong for the amount of uv you are willing to spring for, get a small pump
to run the uv you get. I have 80 watt uv's for both ponds, but that is due
to the size of the pumps. I have seen ponds of 9000+ gallons cleared with
small 16 or 20 watt units.


With 2 "tee" fittings and a gate valve you can easily control the flow
via the UV.
