Take your water sample to your dealer if they have a computer analyzer.
If they are selling Baqua, they should have the same setup as my dealer does- they can test baqua water or bromine (not sure about chlorine).
They can tell you what to add to correct your water. Ph decrease should lower your Ph and alk readings, you might have to add quite a bit.
I have to add over 20 ounces to new water because my alk is so high.
As Hot tub man said, baking soda will increase your alk readings a lot, and your ph a little.
