Yes we have pickerel and some other plants I will post picks of. Starting using a fountain to control algae and now I have a leak under the waterfall and even though this is more of a garden pond forum I was looking for ideas to fix the leak and rebuild the waterfall. I have bentonite with a rock wall dam no liner. Hoping to find some honest reviews of soilfloc? Have seen some people claiming of killed fish and I sure don't want that! Also thinking of pouring concrete for a new waterfall foundation?WELCOME ... ok so what kinda ideas are you looking for ? how to control the algae? what type of algae or aquatic plants are growing in the pond do i see pickerel rush ? more pics help for what ever questions you m ight have
