I just noticed that after adding a little bit too much of this highly potent liquid my last waterchange, blue green algae started to reappear. Prime says it removes or detoxifies nitrates, and BGA thrives in low-nitrate situations, so it might be causing this. I'm thinking that maybe I should switch back to stress-coat or something if this keeps going on. Why would you add nitrates only to have them removed? Anybody have any experience with this?
