Interesting that you mentioned the reagents. Mine have been around for a while and they are kept in the garage at the mercy of the temperatures there. I purchased new reagents today and the results were exactly the same. So much for that. I’m trying small amounts of muriatic acid to see if it will bring down the stubbornly high Ph. I know this will lower the TA too, but I understand I can bring it up a bit with baking soda which should only raise the Ph slightly. As for the TA, it comes out of my tap at 60. Interestingly enough there seems to be two schools of thought regarding TA. One is that low TA will create unstable Ph so the TA needs to be 100 to 150 ppm. The other opinion, which I have seen several places to include this forum is to forget about TA and simply concentrate on Ph. No wonder people are confused about spa chemistry. To answer your other question, my bromine levels are right on the money

What is your sanitizer? Bromine What is your pH? It tests 8.2+ out of the tap, the TA tests at 60 or 70 How are you testing pH and TA? A standard testing kit, not strips Note - I am in South Florida. They add a lot of liquid chlorine to our water because it comes from the Biscayne Aquifer and it is naturally brownish. This is an aesthetic thing, but I understand liquid chlorine has a Ph of 13 and that may be why our water Ph is high.

Hello, this is my first post. I need some advise on how to balance Ph and Alkalinity in my spa. The tap water in my area is high in Ph and the alkalinity is about 60. I know in order to keep the Ph levels in the correct range I should address the alkalinity first, or so I’ve read. When I do that the Ph goes up, and when I try to bring the Ph down the alkalinity goes down. How do I achieve balance without having to play this ping pong game every week? Thanks!
