Hello again,
Sorry to be a bit slow on the up take, only I also have fish in the tank and I was always under the impression that you should keep the PH stable.
So if my Co2 is low in the morning and then builds up during the day, Ergo the PH drops only to rise at night when the gas goes off, then surly this is not a stable PH
Is that correct. How to I keep a happy medium. I.E. I want good plant growth and at the same time have happy fish.
