From the testing:
Chlorine--no measurable chlorine.
pH--VERY High, above 8. Took 10 drops to get back down.
(Need muriatic acid?)
Alkalinity--140 (slightly high, but acid will bring back down also.)



I have read the threads and other posts and find the whole thing
a bit confusing. I think I need to add muriatic acid to bring down the
pH right?
