Well it seems I have very soft water here in Salem Oregon. My GH & KH both register no more than 1dKH and 1dGH. I plan on introducing CO2 using a 5lb CO2 tank, etc. My ph is around 6.3. Will the CO2 drop the ph too much? What should be my concerns? And what are possible solutions? Or don't I have anything to worry about? Sincerely, William Bragg
