So I buy my ferts from GLA and I follow the estimated index. I noticed my nitrates and phosphates spike real high when I dose my macros. I have a good amount of fish in each tank. I’m sure they are producing nitrates as well. Do I cut back on KNO3 and KH2PO4? I’ve been fighting black hair algae for a while now in two of my tanks that have Eco Complete substrate. Does any one else have this issue? I have a 20 gallon, a 2 gallon, 1.5 gallon and a 7.5 gallon. In the tanks where I’m using ADA aqua soil, haven’t had any Algae problems. Any suggestions? Do you keep your nitrates and phosphates at a certain level for your planted tank?
