Yesterday I disconnected my solenoid from my pH controller and connected it to a timer to turn CO2 on and off with the lights (actually on about an hour before lights on). I have a KH of 12.5 so set the bubble rate yesterday to give me a pH of 7, so around 43mg/l of CO2.
This morning after the CO2 being off for over 12 hours, the pH monitor is showing a pH of 7.58.
I know that pH variances shouldn't pose a problem but is there a limit? Here we're talking almost 0.6 of a variance. Is this still tolerable?
