I just drained and refilled my pool two weeks ago due to high CYA and CH. As most of you know, Arizona is notorious for its high CH in our fill water so it can creep up pretty high after a few years.
In any event, after the refill my CH was 150. I know the recommended range starts at 200, but I was wondering if 150 is fine for me since it will naturally raise over time or do you think I should still raise my calcium?
I know my CSI is what I need to watch out for with low (and high) CH, but also that my PH plays a bigger role in CSI than any other factor. If I maintain higher range of PH (7.6-7.8) to keep CSI in check until CH goes up naturally, will that work? I would ultimately like to lower my TA, but would hold off on doing that for now, since that requires lowering ph to the low 7s with muriatic acid. Doing that would put my CSI too close to -0.6
Here is my latest test as of this morning:
FC: 7.2
CC: 0
PH: 7.7
TA: 120
CH:150
CYA: 40
Water Temp: 80
