Have you found a difference in bromine tabs?
I bought a 10 Lb bucket of MaxiBrom ( 86% 1-Bromo-3-chloro-5, 5-dimethylhydantoin) for $90 but I'm thinking I should try another brand to see if I have more luck with the bromine floater getting the sanitizer level to rebound. I shouldn’t have to shock after every use with a floater.
In one article these were recommended-
In the Swim, LeisureTime, Spa Choice
Ours says Slow Dissolving which I thought was a good thing so you don’t have spikes , but maybe we need faster acting?
