peat moss co2
Im wanting to purchase two gbr that require softer water. But If i have hard water, i have read that using peat moss lowers pH. But if iim using diy co2 and using peat moss two..is it possible to get an accurate reading for kH, pH and amount of co2?
Others say using RO water would be better but I no nothing about RO when using co2 and the effects it has in my tank.
