Ok. I set the light timer for only 6 hrs a day. I don't have a good way to raise the light up higher. It is a 24” Finnex Ray2. The legs don't extend up. I could maybe 3d print something, but id worry it would tip over into the tank.
I’ve been dosing with KNO3 for nitrate and KH2PO4 for phosphate. Still have to mix up my K2SO4 for a little more potassium. CO2 injecting from a bottle with pollen glass diffuser, maybe 1 bpm. Only a couple otos in the tank so there is no rotting fish food.
