I am not trying to target a specific PH, but I thought the idea was to avoid PH swings. I do have an airstone that turns on when the lights go out to ensure there is adequate oxygen at night.
Are the nightly PH swings a "don't care"?? Turning the CO2 off at night would be nice since the only thing it does during that time is maintain the PH level.
Thanks for any opinions!
