Has anybody used baking soda (Sodium bicarbonate - NaHCO3) for this
purpose? I'm hesitant to use commercial buffers, because they
sometimes contain phosphate (which i DON'T want) and probably Mg or Ca
as well. I shudder to think what would happen now if i started a CO2
injection system without increasing alkalinity. Pickled fish. Ugh.


Many of us use baking soda every week for exactly that purpose. Buy the
good stuff-good old Arm & Hammer costs me under $2 per year.
