TA always high

Yeah I'm sure your right but I'm still using the cheapo test kit and it won't test PH in the tub... just looks blue. I'll get the FAS-DPD test kit and then maybe it will be easier. Thanks.

If you are using bromine in the tub then you need a special FAS-DPD test that is calibrated for bromine (taylor K-2106 is the complete kit. I forget the number of the stand alone bromine FAS-DPD test for bromine). You can alwasy use an OTO test since you are only interested in total bromine. Many of the cheapie test kits have a problem testing pH in a bromine system because of insufficient halogen neutalizier in the reagent. The Taylor pH reagent does not have this problem.

I switched to chlorine last year when we put the pool in. I figured it made sense to use the same in both. Bromine always made the tub smell bad.

Any reason not to use chlorine for the tub? Seems like a lot of people prefer bromine but I'm not sure why.

none at all! I actually prefer a chorine tub to a bromine tub. Clorine is a bit more work to maintain the levels but if you 'give it 5 minutes a day' like CarlD always says it's not a big deal! Bromine has a strong 'chemical' smell and many people are allergic to it.
