Have a FOWLR and got a second outbreak of what appears to be Cyano algae. It seems to come off easily with a scrub brush. To avoid in future I took the suggestion of some posts and will be adding 2 circulation pumps (Hydor Koralia 3rd gen 1950's). Tank is 48" wide. Is this enough circulations or should I go with the larger model? The LFS suggested it could be a PH issue as well. I've never monitored PH before. Could this be part of it and should I monitor and dose PH as needed?
