So I'm having trouble understanding my new CO2 system. :? I set it up as the big book says but something just isn't right. I'm using a drop checker with the 4dKH and the Hagen PH test kit, adding about 2 bps of CO2 and the checker seems to be all right. It's green-ish. But when I check the PH of the water it the results always way over 7.0. Around 7.6 - 7.8, bright blue!! If I'm right the PH should be around 7 when the solution is green in the dc. The KH is around 8. I'm confused. Should I increase the bps or just ignore the ph test and wait to see what happens? Any ideas?
