I am in the process of closing my pool for the winter. I have balanced the water for a perfect Pool Math CSI of 0.0 at the current temperature of high 60s. When I use the Pool Math calculator and change the temperature to 40 the CSI drops to -0.4 to -0.5.
How does everyone handle this change in CSI versus temperature? If I balance it for a 0.0 CSI at 40, the CSI at the current 60s is +0.4 to +0.5. And all this will happen while the pool is closed and covered so not much opportunity to alter things after the fact.
