New to this forum, but have used this site for the BBB way for our spa other than I use Bromine not bleach. Ok here is the question:
TA is at 40 which is low, pH is at 7.2, Bromine is at 15ppm, which are in the perfect range.
So, how do I raise TA without changing pH? Or should I not worry about it?
We have the iSpa 230 gallon (JUST LOVE IT)!
