It's been a month since my pool was plastered with NPT ColorScape Caribbean Blue.
PB started up the pool over ten days to gradually balance the water.
After start-up, water measurements have been pretty consistent as follows:
CC=0 ~ 0.5
To prep the water for borate, over the past few days, I tried to lower TA to 80.
Over five days with pool covered for preserving solar heat, I kept pH at 7.2 with IntelliChem. TA does not seem to change a bit (still 120).
Yesterday, I removed the pool cover, stopped IntelliChem at 7.2 and aerated over night.
This morning pH was 7.7 so I manually poured half gallon of muriatic acid to lower pH to 7.1 and continue to aerate.
So my questions are:
1. Is it too early to add Borate to newly plastered pool?
2. Should I lower pH to 6.8 to compensate high CH during this lowering TA process?
3. What would be the lowest safe pH level for newly plastered pool?
