Last night I turned on my pressurized CO2 system for the first time and within an hour I had almost killed my Kribs. It turned out that I had a drastic drop in PH. From 7.2 to less then 6.0 (I don't have a test that goes below 6.0 but after 50% water change and the rest of my PH stabilizer stuff I only got it up to about 6.6).
So what's the deal? I can't imagine I had put in sooo much CO2 in under an hour that it overwhelmed my tank and caused the PH crash when people here leave their CO2 on 24/7.
I clearly need some buffer to control the PH. So I tested my KH to see where I'm starting. KH read at 7 DH. Does that explain what happened to me? What do I add to keep PH level? Baking Soda? Not sure I want to put crushed coral in my freshwater tank, but... would it work in my canister filter? Am I even going in the right direction?
