Checking the CO2 in mid afternoon I find that pH is 7.6 and KH is 10dkh =
7.5 ppm CO2, in the morning after lights on for a couple hours it checks, pH
7.0, KH 9dkh, CO2 = 27 ppm. Is this depletion good, bad or indifferent.
Should I be looking at decreasing my surface agitation of the power filter?
Thanks.
