I try many products to kill that red algae. I try Algae Magic, Chemy pure, Red Slime remover, ... I turn off the light 2 for during a week and then it grew up again. I took all the rocks out to clean it outside but that does not work. I have the red algae in all my tank (glass, sand, rocks, equipment in the tank,...) Can someone give me some ideas to kill that algae?
