I've just completed my initial setup of a SWG system with Borax and would appreciate feedback on the current measurements and any recommended changes:
FC = 5 (am still adjusting but plan to keep around 5 ppm because of unpredictable heavy bather loads.)
CC = 0
pH = 7.7
CA = 100 (TA corrected for CYA)
CH = 340
CYA = 65 (planning to ease this up to 70)
Borates = 45 (as best as I can read the test strips)
NaCl = 3200 ppm
Temp = 85
According to ChemGeek's spreadsheet, the Calcite Saturation Index comes out at 0.00. Is this too good to be true, or am I missing something that needs to be adjusted? Also, I've read some discussion between ChemGeek and Waterbear about some advantages to moving CA a bit lower. Any thoughts on that?
Thanks for all the work you pioneers have done and reported here and on the Pool Forum!!
