TA still low

[Chu1ck]

Pool looks great. Water temp is high this time of yr in the VI's (86 deg).
FC and TC fine 3.5ppm pH fine 7.6 but TA always seems to be low 50-70ppm. Have added TA+ but I'm hesitant to add more Baking soda for fear my pH will skyrocket. Any thoughts?

Welcome to TFP!

Have added TA+ but I'm hesitant to add more Baking soda for fear my pH will skyrocket.

Baking soda has virtually no effect on pH.

Total alkalinity indicates the water's ability to buffer pH changes. If your pH is relatively stable, I would leave TA where it is, but I wouldn't let it get below 50 though. If you do need to increase TA, go ahead and add the proper amount of baking soda and don't worry about any adverse impact on pH.

Yep leave TA alone. The higher the TA gets the faster PH raises.

How are you testing? The TA test in the recommended test kits does not result in a 50-70ppm range.
