Hi Susan I had a tank that was badly plagued with blue green algae for a long time and I couldnt get rid of it at all. Eventually I got it to die off by dropping the pH to 6.0 and loading the tank with tannins (heaps of peat in a stocking) after 3 -4 days the algae started to die off, which I then siphoned out on a regular basis. I was told by a LFS owner that bg algae cant cope with tannic acid. IMO this is better than treating with antibiotics, but I guess you need to decide which the fry would handle better.
