CO2 Injection is raising my KH.. but lowering PH. What the hell?
I'm completely confused.
I just started adding Co2 and am trying to guage how much co2 is in my tank. When i tested my water params two days ago I had a KH of 2.5 and PH of about 6.8. Yesterday KH was about 3.25 PH 6.5-6.6. Today KH apparently is 4 and PH is 6.4-6.6.
I've been slowly increasing the amount of CO2 in my tank to find the correct BPS.
Any help? I have planted tank with some rocks and Aquasoil in my tank.
