I used to use Phosguard and then read that it leaches aluminum. Is this true? Instead I use nothing but treat tank weekly with Phosphate E. My Phosphates hoover at .05-.06. I am constantly dealing with cyno outbreaks. Could Phosphate E cause this? Used chemiclean in past but still comes back. Usually on lower rocks and sand. Thinking of using Dr. Tim's method.
Any ideas and help would be appreciated. Could 7 mo old T-5's cause this?
