Saturation Index (SI), SWG, and Above Ground Pools

I have a 16x33 AG pool with deep end to 6 feet. Volume about 14,000 gallons. I have a Pool Pilot Digital with a SC48 Cell.

Current readings:
Temp: 80F
PH: 7.2
TA: 60
CH: 60
CYA: 30
Salt: 3200
FC: 4.5 - 5.0
CC: 0.5

TDS: ???

With a vinyl liner, I have never concerned myself with CH levels and only maintain TA to stabilize my PH. With my new SWCG, do I need to be concerned with maintaining a proper Saturation Index to preserve my SWG Cell?

With the above readings, my SI must be around a -1.5 (goal being 0.0 +/- 0.3). By the book, this makes my water more (much more) corrosive.

Should I focus on raising my CH, TA, both... or not worry as I have a vinyl liner?

Thanks - Bob

Hi Bob,

Thanks for selecting Pool Pilot.

With SCG systems, there is little concern with water chemistry in the corrosive side. With the SI in the scale forming side, there is a greater tenedency for calcium scale to build up on the blades, which is not good.
I would recommend increasing your CH to about 200 ppm.
Leave the TA where it is.

Thanks Sean,

An easy and uncomplicated adjustment. Just as pool care should be.

PS - Pool Pilot has been installed/working for just under a week now. While I have been taking daily CL measurements, I haven't had to add any CL and have been maintaining FC of 2 to 5 with swimmer loads of 3-4 kids 2-3 hrs/day. This Summer should go smoothly.
