UV Sterilizer/Clarifier question
Hi everyone. We are seriously considering investing in a uv sterilizer/clarifier for our pond. It sits in full sun all day, and we are at our wits end. We get it cleared up, and it goes back to green again. We have tried every bit of advice on this forum that we could, and although it is getting a tiny bit better, we know whats coming! Our pond is about 1200 gallons. One half is about 13" deep, and the other is 2' deep. Our pump is a sump pump that said that it is for pond use as well. It is 3300 gph. Can someone please recommend a good uv product to us, and also what size. My head is spinning from searching online and getting so many opinions. Also, we have water hyacinth, and water lilies, but they currently cover about 25% of the pond. Thanks in advance for any help.
