Stable Ph with SWCG....is this normal?

[waterbear]

The only thing that will cause TA to go down it adding acid. If your pH is staying stable enough for you now don't change it but as chem geek and I said before, most SWCGs seem to exhibit the BEST pH stability with the TA at around 70 ppm and 50 ppm borate (with CYA at the manufacturer's recommended maximum) and there is several years of evidence in actual pools to back this up from various forums and other sources.

Thanks for the info. Since my pool is stable with no current issues, I'll just leave well enough alone and just enjoy it. Now off I go for a dip in the pool!

I have seen this as well. My pH started at 7.2 with the fill water. It came up to 7.4 after a night of rain, and hasn't moved since. I'm using the Intex 1600 gpm pump with 14" sand filter/SWCG combo. I over-shot the salt and am at 4400 ppm, TA = 120, CYA ~ 60. I run the SWCG for 2 hours/day and FC holds right at 8 ppm consistantly.
