Hello, I've been dosing vinegar as a method of lowering my nitrates and i am dosing quite small quantities for my tank. Tank is a 75g with a 38g sump. Right now i'm at 7ml daily and already have slime everywhere, how can i control this problem? it has happened to me with nopox too but it was much worse. I know of people that have this problem but usually on high dosing quantities, at 7ml i don't think i am even close to half what my tank size recommends. Is there any way i can battle this?? Thanks
