New plaster pool, and the pH keeps rising to 8.2, it just loves it there. So, I am thinking about keeping it there; between 8 and 8.2 (in the winter and when ready to swim, temp at 74, keep pH around 7.8)
FC .38 (I know it is low, and I do have UV)
CC .24
pH 8.2
TA 100 (pool maint decided to add bicarb last week, I guess his way of trying to control the pH from increasing every week; will ask to leave it alone and keep at 80max)
CH 180
CYA 40
Temp 61
So I am calculating SI at 0.25; which is good in my opinion, when TA goes to 80, I will be at 0.13.
I was a bit annoyed when the guy was adding powder to my pool, I asked what he just added and when he said bicarb, oof. So, before I have my talk tomorrow with him, what do you guys think about having a high pH pool like this? It is new (couple of months) and it is zero edge with a tank, so aeration adds to the high pH. As long as the saturation index is within -.3 and .3; I should not have any issues and then warmer pool temp, higher calcium by summer, I can drop pH for comfort and FC efficiency. Am I missing something? My main concern during winter... pool equipment, plaster look/scaling.
In case you are wondering, pH / SI history:
Day 1 7.8 SI -0.17 (treatment from 8.2)
Day 2 8.0 SI 0.06
Day 3 8.1 SI 0.15
Day 4 8.2 SI 0.26
Day 5 8.1 SI 0.17 (rain)
Day 6 8.2 SI 0.26
Day 7 8.2 SI 0.26
