That's my question. I have a gunnite pool and need to know pool parameters that are best for closing. We cover the pool with the old-fashioned tarp method (not porous) and our water temperatures get as low as 45 degrees farenheit in the winter. Currently, I have:
pH of 7.5
TA of 90
CH of 280
Cya of 32
The CSI re: the pool calculator with a current water temp. of 80 degrees is -0.02. What would be optimal closing parameters upon closing? ( I have a suspicion that both pH and TA rise and I know that Calcium becomes more soluble as the water temperature decreases.) But, we do not circulate our water during the winter, so I wonder if the parameters matter when the water is just still.
Thanks,
