I started opening the windows this past week in the mornings and wow has the pH been boosted. I already have an outside airline to the skimmer and an erv in the basement, but nothing does high pH like opening the windows. I recently bought a Co2 meter and it's never really above 500 in the basement normally (outside air is about 400), but fresh air makes all the difference. Alk is about 8.0 tested daily, and hasn't budged. Kalk plus calcium reactor plus 24x7 refugium included.
