Argh! I've had a 3,000 gallon Endless Pool for about 6 years and I never had any trouble balancing the water until I recently had to leave the pool alone for a month (the pool has separation anxiety, apparently). Ever since then, it's been nothing but trouble. I've gotten most of the levels under control, but the chlorine simply won't behave. I get high combined and low free no matter what I do. Just now I got .12 free and .45 combined. I decided to add the amount given using the TFP calculator, and that was 1/4 cup of 8.25% bleach.
Can someone tell me the right amount of bleach to burn off the combined and leave me with some free chlorine?
