RCS tank trouble
I am having a problem in my cherry tank. I have had quite a few deaths since last week. I've tested params last week and the only alarming thing was nitrite was 1.0 and nitrates was 40(always have been this high even with floaters). After seeing params I started doing daily water changes. Well after a long day of work yesterday, I was unable to. Tonight, I tested params again and this is what I get:
What could be the issue? I was dosing with ferts(macro,micro) and also running co2(1 or 2bps) but have stopped since the deaths. This is in a 20G long tank.
Any help would be appreciated
