fill water test results

I'd probably go with about 3.5 lbs. of stabilizer for starters. See how high that takes it in about a week. (Don't test sooner than that or else you're just wasting your reagent.)

I wouldn't take the FC so high. You are right that with no stabilizer it will come down fast, but I wouldn't take it that high. Don't want to risk bleaching the liner.

Watermom's absolutely correct. FC's high if the pool is clear because your CC is 0. pH is low. T/A should be ideal. Calcium is irrelevant, unless it's too high--and that doesn't happen till it hits 400.
Figure your pool at 13,700 gallons if your water depth is 4'. For quick calculations you can use 13,500 or even 14,000 and there will be no significant difference.
If your pool is clear, I'd let FC come down to 5, but no lower than 3 (I just am paranoid about levels under 3ppm).

My numbers this evening,
FC-10.5
CC 0.5
PH 7.0
TA 100
water is starting to look a little cloudy. I can't seem to get the PH up. I added another 50 oz. of borax today, and also aerated for a couple hours today and didn't help.

You only have to wait about 2 or 3 hours after adding Borax before testing pH again and redosing if needed with more. Keep testing and adding bleach a few times per day and run your pump 24/7 if it is looking cloudy. You'll get there.

After adding the borax yesterday I ran the Polaris 64 for several hrs. It releases excess pressure at the return line so it also does a fair job of aerating. I can see the bottom but my water still looks cloudy with a slight yellowish tint to it. I almost want to add some bleach but my FC is still high. Also it is not falling as much as I expected. Should I remove the sock with the stabilizer? I didn't check the CYA yet because it's only been a couple of days since I added the stabilizer ( one sock full dissolved already). Anyway my numbers this morning,
FC: 9.5
PH: 7.4
TA: 110
CC: 0 (maybe I did this wrong yesterday, it wouldn't just drop without doing anything would it?)

if you added enough stabilizer for 30ppm, just leave it to keep dissolving; if you think you added to much, you can take out the sock then measure CYA in a few days, and add it back later if needed...
the aeration is going to increase your pH, so I'd leave that alone for now; be ready to add acid later to keep it <7.8...
If your water is cloudy, maintain shock level of FC as if the CYA was completely dissolved- IOW, if you added 30ppm CYA, then use 30ppm CYA to determine your shock level even if it doesn't show up on your test yet...

[madwil]

also, the aeration will increase your pH, so don't add to much borax- I'd adjust pH to 7.2, and let it creep up on its own with the aeration...

[CarlD]

I would check the stabilizer level, just to be sure it isn't too high. Let us know the number.

CYA looks to be slighty less than 30. Black dot doesn't disappear at 30 but it does when tube is full, which is just a little more.
