Quote from: klondike on Yesterday at 08:45:59 AMHow about a UV filter to kill the algae? That can't kill the fish. I don't know how effective they are as I've never fancied the problems a pool presents but I do know it was what one neighbour had.Our huge filter has UV, it shifts up to 60000l per hour, what we have is blanket weed..the stringy algae. , just on some of the edges of the pond . I am wary of using chemicals at this stage of my koi ignorance so I will continue to hand weed and keep aerating
I also remember the cursing I heard coming from another neighbour years back. Turns out he'd use the wrong concentration of a chemical fix and had killed off a lot of expensive koi.
