I know you shouldn’t chase pH, but I just watched the BRStv episode about scrubbers and wonder if I should get one. My pH runs between 7.8-7.9 in my 40g fowlr tank. Alk is 11, Ca 490. It’s going to be an LPS dominant tank and I’m planning ahead. I’m almost positive it’s a CO2 issue. An air line outside is impossible. I’ve been seeing info that corals calcify better at a higher pH. What does everyone think?
