Trying to stay half a step ahead of the game; I was wondering what to do as the pool cools off this fall and winter.
I'm in TX so I'm not going to close it but have noticed that as the pool temp falls my balanced numbers now:
pH 7.5
FC 5
CC 0
TC 5
TA 90
CH 340
CYA 40-50
Salt 4400
Temp 86F
CSI -0.17 ("balanced")
...become more and more (potentially) corrosive, or negative.
I know that CSI is affected by many factors but it would seem that pH, in this instance plays the biggest part.
Is the solution to this, low temp, potentially corrosive CSI just to let my pH drift up (as it naturally does - SWCG!!) to around 7.9, as opposed to 7.5 as the temp falls? Or am I over simplifying things?
Thanks again in advance.
