Gman,
Unfortunately, I do not have the numbers prior to the addition of the gentle spa. I measured my PH 3 days ago and it was 7.6 (it was in the range 7.5-7.7 for a couple of months). Also, my TA was 60 2 or 3 months ago. Since then, I didn't measure it until now. After the gentle spa, it was 80. Now, I'm lowering it with dry acid. I use the CYA then bleach method (I add stabilizer right after the refill). I added 16oz of gentle spa using a postage scale and a plastic bag.
Regards,
oldparr
