Just wondering everyone’s experience with Red Sea Nopox. I have 75 gallon currently fish only with high nitrates, so I wanted to try Nopox been using now for 4 weeks with slowly lowering nitrates. I noticed white film on glass within first week and just noticed pink slime in sump only a small amount. I started with half the recommended dose and slowly working up to full dose. I have performed 2 water changes 30 gallons each since starting. Just wondering when this white film/slime will go away?? Any advice?? Hoping to get nitrates/phosphate within normal levels to eventually add beginner low light corals.
