HI I,m new to this site and so far think it is great . I look forward to useing it and hopefully getting to know some of you. I have a 150 gal. tank mostly fish . I do regular water changes and all my water quality test always come back wonderful, virtually no traces of ammonia or nitrite even nitrate is almost nonexistant. But my tank is always plagued with brown, green and red slime algae. There isn,t any more desireable growing .So if anyone may have some tips on getting rid of the slime and growing something more benifitial. Please Help.
