Sounds good all, thanks for the tips. It has been in the tank for about 3 or 4 months now. I kept thinking it was gonna go away, but it just kept getting worse. I have cut back drastically on feedings, and I am doing larger more frequent water changes. I am NOW aware of the root of the problem, and I don't like adding unneeded chemicals, but I am tired of looking at this stuff. I thought if I could get rid of all of it, then it would be easier to control it in the future. As far as flow, I believe it does help. One day I left for work and when I came home I noticed one of my pumps had lost its suction on the glass and was pointing directly on a rock, and that spot on the rock(in just a few hours) was almost completely cleaned of the cyano. Thanks again for all the help.
