Is a general hardness "booster" needed for a planted tank when using pressurized CO2? For the life of me, I can't seem to find a simple answer.
I understand that CO2 dissolved in water = carbonic acid and I guess my ultimate question is: Is the general hardness booster used as a buffer against pH changes? Is it really needed and, if so, what is the ideal target hardness? If it's not for buffering, why use it?
My water is relatively soft, according to a former worker at the local...
