| Steve I fought the stuff your years without success. I tried massive water changes (up to 30% a day), draining the pond and sterilizing the walls with bleach, using Clarosan to poison it.
The only thing I have done that actually worked was to make a TT that put 50% of the water through it an hour. I used clarosan to kill off the week first and in combo with the TT it never returned. Clarosan alone will only knock it back for a month or so. The down side was my water went completely green for the whole summer. With luck it will reach a better equalibrium this spring and I will have no further trouble. That said i would rather have green water than stringy algae. The string stuff acts like a crap trap and keeps all kinds of rotten junk in the pond and NOT in the vortex where it can be flushed away. Bad news. My fish had all sorts of trouble and the water had a terrible level of bacteria. No more trouble now and health isn't an issue anymore.
