A health club pool contacted a local inspector with an unusual problem: their ~25,000 gallon pool won't hold Bromine levels at all.Even after shocking, the Bromine level won't pass 4 ppm. The next day, the Bromine level is barely detectable. These folks are literally shocking everyday and spending a fortune.The pool has been in operation for 18 years, and this problem started approximately 2 months ago. I've quizzed the manager on what, if anything, changed 2 months ago in regards to the pool/pool operation, and nothing jumps out.The brominator has been replaced. The pool has been shocked, super-shocked, etc. pH, Alkalinity, etc. are all monitored and in range. Their usual brand of Bromine has been replaced with another brand, test kits have been swapped out, etc. UV doesn't seem to be a cause. The sand filters have been checked and, if I recall correctly, the sand has even been replaced.Any ideas!?

  • What is the TDS Level? When was the last time the water was drained and the sand changed/cleaned?
