I filled our new 355 gallon spa and balanced the water to these readings:
78 degrees (still heating)
CH = 190 (up from the tap water of 20)
TA = 50 (up from the tap water of 30)
ph = 7.6 (down from the tap water of 8+)
FC = 8 (calculated after adding dichlor)
CYA = 7.6 (calculated after adding dichlor)
I would like to get the Borates to 50ppm but I don't want to drive up Ph and TA -- or is this inevitable and I'll have to bring it back down with dry acid?
Planning to use dichlor/bleach and using the Pool Calculator. Using a Taylor 2006 test kit.
