I have never heard that UV will kill the parasites too, I'll look into a UV filter. Like I said I have 2 pumps with filter (then those feed into a sort of mini bog style plant filter) and one of them is technically large enough to handle the load but I put in a second one once the fish starting really growing and multiplying. The water is actually very clear. I really don't want to, but if it comes down to it and I do just start over, do I empty thr pond and let it set out dry for a while? Or just cleaned out with fresh water?
No visible parasites but with the water quality being good on weekly or more frequent checks and them flashing thats my only guess.
