I just got a new spa with a built-in Frog system and the PH and Total Alkalinity are very low.
Should I try to raise the TA first or the PH?
Are borax & baking soda safe to use for raising PH and TA with the Frog system?
Is there a guide and chemical calculator for spas like there is for swimming pools?
