I currently have a 3500 gal pond which may need some upgrades. I think I spend more time then I should be keeping it clear. For many years I was using 2 laguna presure flo 3200 filters and 2 jebao stu-55 watt uv sterilizers. With that setup I was running the water through a plastic tote with poly fill one a month to keep the water mostly clear and backwashing the filter weekly. Last year I added an atlantic skimmer, 1 OASE BioSmart 10000 Filter and 1 TMC/AAP High Output 110 Watt UV light. This helped quite a bit but the water still was not super clear. I have an underwater camera and you could see more debris than fish. I just setup everything for the year and I leaks and cracks on the filters. I am debating if I should replace some components rather than fixing them. The pond is around 3000 gallons roughly 25'x20'x3', is under a large tree which drops alot of stuff into the pond, and currently the pond has 50 fish mostly goldfish. I am thinking of cutrting down the tree which would then have the pond in full sun all day.. Also I changed the liner last summer so I took a count as I moved them. What would I I need to change or add to my setup to keep the water clean and clear. The pieces leaking are fixable and I can do it myself if those filters should be sufficient. I would like to keep the bill at <$3000. Any guidance would be appreciated. Thanks.
