pH, pH, pH

My tank’s pH averages about 7.7. I run a CO2 scrubber which helps a little. Without it, the pH hangs at about 7.6. I would LOVE for it to be about 8.1 or 8.2. I can’t run an air line outside and leaving a door or window open isn’t possible. Does anyone have any suggestions?

Kalkwasser will bump your pH up as a nice side effect of adding alk and calc. Are you dosing to maintain levels in your tank?
