Balanced Pool and Pool Math

[outdoor]

If i have a SWG, vinyl pool how much should i be concerned with the CSI index?

I'm in the middle of adding borates to my pool, but expect when i'm done my readings to be somewhere around:

FC 4
CYA 50
PH 7.5-7.6
CH 100-110
Salt 2900
Borates ~50
TA 80-90

According to these I'm outside the -6 to .6 and my pool is not balanced. Is this because mainly my CH is low and does not matter for vinyl pools anyway?

since i don't really need any CH. If that is the case should there not be some sort of calc that takes it into consideration my pool is vinyl and the numbers to be 'Balanced' should be different?

As long as you keep all your readings within our recommended levels you canalmost ignore the CSI. With your vinyl liner the only worry you really have is CH getting way out of line high and scaling. The corrosive part only deals with plaster pools.
