I normal have lower Ph in my tanks, maxing out at 8.2 with lows of 7.7. I don't see any adverse effect with this range, just slower growth. I started use CO2 scrubbers on 2 of my tanks to keep it around the higher end. The scrubbers worked well for months keeping the Ph up. With the nice weather and having windows open, I've been having elevated Ph in 1 of my tanks, with a CO2 scrubber. The last week it has been going up to 8.45. How high is too high? I know I want to minimize swing. I have my controller shut down my protein skimmer at 8.4. It will stay high for a few hours then come back down to a low of 8.2. I'm not seeing anything bad, just not sure if this will be a problem long term. I'm taking the scrubber offline until I see a drop. Also looking for ideas for maybe a solenoid to divert air from scrubber before shutting down skimmer.
Thanks for any input.
