I don't think LaMotte makes a "carbonate hardness" test kit. Which test kit did
you actually use?
They make an alkalinity test kit with measures in CaCO3 equivalents. To get dKH
from alkalinity (assuming bicarbonates are the only alkalinity producing ions in
the water) divide ppm by 17.8.
A dKH of 2.2 and a pH of 6.1 indicates a CO2 level of about 55 mg/L. I would
suspect your CO2 would NOT be this high - that's a potentially lethal level.

Do you want to know how I did it?
