High PH, should I increase CO2
My tank has about 450GL water and the PH is around 7.34 at before the light on and 7.55 before the lights off.
Should I increase the CO2 dosing? Currently it is around 2 ~3 bubbles per second.
Yesterday my CO2 supply went out the the PH went up to 7.75, I was terrified. I had to change 20% water every other day to keep the PH from shooting up. The KH is around 7.
