TA Test - Me vs. Pool Store(s)

[TSH]

Thanks Waterbear. I suspected at least one of the stores was off when he said the water was acidic based on my "low" TA, yet my pH was fine (actually a touch at the high-end with 7.8).

I have a salt water system. Salt reading is currently 2900 and I have the system set to 20% chlorine generation. I use a powdered acid (ph Down) when I need to bring pH down (it does tend to creep up, albeit slowly). My FC was about 2 when the samples were taken Saturday.

With a SWG try lowering your TA to abut 70-80 ppm. You should find that helps with the pH rise. Also make sure your CYA is at about 80 PPM. That will also help with the pH rise.
