My parameters for the record:
pH - 6.8-7.0
kH - 11
nitrate - 10-20 ppm
phosphate - 1-2 ppm
iron - about 1 ppm
At that high of a KH, small differences in PH means a huge jump in CO2
content.
6.8 = 52ppm
6.9 = 41ppm
7.0 = 33ppm
30 ppm is borderline healthy.
ppm C02 = 3 * dKH * 10^(7 - pH)
Though, I must admit that once I woke up to find my CO2 content at
133ppm. The snails were heading for high ground but the fish appeared to
be OK. Odd. I thought they ought to be dead. They didn't seem to be the
slightest bit sluggish either.
