I have what looks to me like cyano in my 90 gal tank. The only thing in the tank is LR and a cleaner crew. since i don't have fish, over feeding isnt a problem. I plan on changing the flow in my tank around some to hit the effected areas. I also plan on upgrading the skimmer i have. I understand you want to remove as much of it as you can, but if its just a thin film on the rocks and glass how do you remove it? I cut down on the time the lights are on and I use ro/di water. Any thing else i can do? I want to get rid of it before adding anything to the tank.
