Green water is easy to remove with Potash. String is harder. I tried using pot
scrubber last week. I got no where. I'm waiting for the plants to start, to remove
them string.

I have just turned my pumps and UV filter back on about 2 weeks ago. The water
already looks clean, but what to do about all the string algae. Most of it is
attached to upper level rocks, not much on the bottom. Any good brushes to
use. Help
