Hello all,
I got my CO2 up and running complete with PH controller.
I set it up according to the instructions and it seems to be working fine, but the pH keeps going up and down. I have the controller set at 7.0 (my KH is 8 ) and watching the pH meter it goes up and down +/- between 6.9 and 7.3.
Before bed last night it was right around 7.0 when I turned the lights off. Nothing is on a timer so I didn't turn anything off but the lights.
But when I got up this morning the pH was at 8.3; the flow seemed to have stopped entirely (no bubbles in the bubble counter) even though the alarm light was blinking on the controller. So I adjusted the flow control knob on the regulator until bubbles were coming again and it began correcting itself. (I am not entirely convinced that my son didn't tweak the knob when he got up early this morning...he says no, but he is only 4....I have since locked the cabinet up so no one can mess with it.)
I am just wondering how much of a fluctuation is normal? Obviously there will be adjustments in the beginning but in a couple weeks when I put fish in I am worried that the fluctuations will cause stress.
Anyone have experience to offer?
