New to the forum. I have a four year old pond .66 acre that is lined on the bottom with a pond liner. There is a varying depth to the bottom sediment from as much as six inches close to the bank to none at all twenty feet from the bank. The water is extremely clear right now and algae growth has intensified. The water has good plankton blooms later in the year but I am struggling with an algae overload now. Chara (or something like it) covers the pond bottom and FA covers the Chara. Mechanical removal is backbreaking work that only delays the algae coverage. I prefer not to use chemicals due to the toxicity to zooplankton but I am a loss. Really would like your opinions.
Thanks
Bob
