I have just a curiosity question. Yesterday my pH was at 8.0. I was a little worried that I had it too high. My TA was at 110. Today, my pH was about 7.6, and TA at 100. What makes the pH and TA lower that much from one day to the next? I know from what I've learned here that bleach will raise the pH, right? yesterday's TC was 5.5, today was 2.5, so could that make the difference? I was under the impression that if I got TA up to 110 that it would stay there for a while, keeping the pH from fluctuating.
Just when I think I know all this stuff like the back of my hand, I realize there's a ton more I haven't learned yet!
