Default CO2, no need to measure KH ??
wrote:
I found that if I wanted a 'target' CO2 level of 15mg/l this always
resulted in a drop of pH of about 0.7 from the no-CO2 equilibrium
(atmospheric) level for all KH values between 1 and 8

Am I losing my marbles, I've not seen any refs. on the internet to this,
they all require me to test the KH to know the mg CO2
What am I missing ?

Not everyone has a KH between 1 & 8?
