Did my testing with my new kit last night and came up with these (all expected, based on previous pool store tests)
TC: .72 -> CC = .13
From what I've read, CH is of no concern to me at this level at all, and pH is great. However, the pH got there because, when it was at 7.0 and TA was at 80, the pool store told me to bring up pH by raising TA (I didn't even use all of what they told me too), which now seems too high from what I've read.
In the meantime, there's been no stabilizer added, so CYA being 2 is expected but not helping. And FC is way low, I'm sure partially because of the lack of CYA. And I expect that my CC is non-zero maybe because I don't have enough FC.
Now, beyond whether my understanding of above is offbase (is it? Or am I in the ballpark?), I don't know where to start. Should I crank up the chlorine and CYA first? I could put some stabilizer in while I use the IC40 to "superchlorinate" - should I do that at the same time? Or should I worry about the alkalinity first?
