This red film is covering everything and killing off the corals. I tried to scrub it and also use chemiclean red slime remover and nada. I had great purple coraline algae group just months before (see pic). The major change was going from 4x65w PCs to 4x55w T5s. I have 2x175w 10k MH that I ran also.
Red Slime?
