I have a huge problem with Red Slime Algae. From the last time I checked, I had a Phosphorus level of approximately 1 ppm. I have recently added Phosban to the water and it did very well at controlling the Green Algae but it did nothing for the Red Slime Algae. I was told that Red Slime Algae is an aerobic bacteria that requires a poison of some sort to kill it. Anyone know of nonpoisonous ways of killing it? It is really getting out of hand here. :-?
