Some Numbers After 5 Days

I started the pump Monday evening. I added the salt and started bringing the CH up. Tuesday morning I added the Jack's Magic and started adding stabilizer. Tuesday night I shocked the pool, turned on the SWG and finished adding stabilizer. Wednesday I added more calcium to bring the CH up.

Numbers as of this morning:
FC - 5 - a little high but holding steady over the last 36 hours so that is good.
pH - 7.6 without me doing anything yet
CYA - will wait till next week to test.
CH - 150 - still a bit low, I want it around 200
TA - 80. Pool school says TA for salt pools needs to be 50-70 but this is how it came out of the ground, so I will take it. Last year it was 120 from the well.

I have a sequst test kit on order so I can figure out a dosing schedule for the Purple Stuff. I also have a timer coming. Right now I turn the pump on before work and turn it off around dinner time.

You seem to be doing very well.

With a vinyl liner pool there is no reason to add calcium, though it doesn't hurt.

All in all that looks pretty good but you don't need to worry about the CH in a vinyl pool unless you have some equipment (i.e. heater) that the warranty requires you to have it at a certain level.

With the CH, I didn't think so for vinyl either, but the folks at Jack's said their products work best with CH at 200-240. That could also be they assume a CH around that level when developing the products so don't do much testing at different levels, but based on my experience last year with the old pool, I had a lot less issues once I raised the CH.
