Got up this morning and tested the water first thing:

pH: > 8.0

CH: 50

TA: 160

FAC: 1.0

CYA: 30 ppm

550 gals, 104 degrees F.

This was after about 1.5 hours of use last night. So obviously I need to add bisulfate to get pH down, but should I add some calcium to raise CH as well? I also added borax to approx 50 ppm borates based on the poolcalculator.com results.

You need to get TA down to 40-80.

Lowering TA will lower PH.

Use Nitro's aeration method once PH gets down to 7.2 to raise up to 7.8. Rinse and repeat.

So after a couple of adjustments this morning here is where my water stands:

- pH 7.6

- CA 130

- TA 80

- FC 3

- CYA 30

This works out to a CSI of -0.16.

I am pretty happy with these results, but I am looking for some input from the chem experts.

I'd call that near perfect. The (-) CSI is fine.

Looks good. The 130 ppm CH should prevent foaming. If you find that the pH rises over time too much, then you can lower the TA more; otherwise leave it as is. The pH might lock in around 7.7 anyway.
