I have just hooked up a DIY co2 system to my 77g tank. I took a water sample
and found the parameters to be

PH 7.6
KH 50
GH 80

does the KH not sound low in relation to the PH level and if so what if any
concerns should I have if the CO2 drops the PH level I would assume it would
also drop the KH. Comments, advice please.
