I just did my water testing and here are my results where CSI = -.23
Temp is 35F
I noticed when I used the pool calculator, if I adjusted the ph to 7.6, it would change the CSI to -.39! I always thought I need to keep my PH around 7.6 to 7.4? However, the CSI shows it to be more dangerous. I was thinking to partially refill to bring the CH down to 300 but it also showed a drastic change to CSI to -.53. How does CH affect this? Please advise.
Also, to partially refill, can i just put the hose at the bottom of the pool and let it run?
