I have just posted a question about my pump. Now i noticed a lot of string
type algae in the corners of the pond and a lot of algae in the filters them
selves, but the water is clear and test strips say water is good. I made a
skippy type filter which worked great last year, but this year, not so
great. Have the same amount of fish. My water hyacinths are doing really
poor. They won't grow, just seem to turn brown or just stay the same....Any
help? Thanks......................
