Hi, I keep reading in all the threads about uv filters. I have a pond that is 7ft long, 5.5 ft wide and 3 ft at the deepest part. What is a good UV filter for this size pond. I have been using an old pool pump and filtration system which worked well when it was 90 percent shaded, but with the new pond out in the open with nothing to shade it except the gazeb it is in I am having very green water.
Thanks
