I had a previous problem with algae which I cured successfully, but now I
am suffering with a sludge issue. I have a pond that is 5m x 5m x1m and
has adequate filtration and plant cover. The fish are not overfed, and eat
everything I give them. I now have a green sludge forming around the
plants in the pond and covering the base, it clogs over the pump and is
very difficult to remove.
Any advice to what could cause this issue? Would pictures of the sludge
help?
=========================
It may be time to drain and clean it out. We do ours at least every two
years.
