I have a 3200 gallon pond and I can't get the water clear. I have all the bells and whistles but the water is still so green I can't see my fish. I have an EVO55 UV light and the pond is still green. The pond guy I bought it from assured me that it would clear up the water but it hasn't (and yes the light works) and I'm about ready to give up. There is no business around here that I can hire to look at my pond. Any one have a suggestion that works I'll be forever grateful.
