CO2 and KH
I have a new tank that's running pressurized CO2, remineralized distilled water, and UNS Controsoil buffering substrate. I originally had it set to 5 degrees GH and 0 degrees KH due to it being prepared as a caridina tank. However, my cycle has been very slow, and I read that increasing pH would help the bacteria propagate. Today I raised the KH to 6 degrees. Normally my drop checker turns lime green following CO2 injection throughout the day. However, after raising the KH it reads a dark blue. My CO2 settings are the same. I wanted to ask if anyone had any experience with this, and if it's fine to leave my CO2 injection at the same rate, or if I should raise it until the drop checker turns again?
