daily drop in ph a bad thing w. CO2?
I have a pressurized co2 system set up to run during the day and notice in the morning the ph is 7.8, and by the end of the day its at 6.9-7.0. Is this daily drop in ph and then increase over night a bad thing for my discus fish? I have noticed that one of my discus, hangs out at the top of the tank the last hour or so of co2 injection. Once the co2 kicks off and the airstone starts, he is back to his normal routine. any ideas?
