I work at a large (860,000 gallon) high use pool and have had high levels of chloramines the last couple of weeks which started in the middle of a large swim meet with approximately 860 swimmers.
We are coming up on another large swim meet and my combined chlorine is still running at .7 ppm. FAC = 2.4 ppm and TAC = 3.1 ppm
I am considering breakpoint chlorinating the pool Saturday night in preparation for next week but I am worried that I will not be able to get the chlorine back down to a legal level before Monday AM when we are open to the community again.
My plan is to breakpoint chlorinate Saturday evening. Then backwash to waste, vigorously, taking maybe 6 inches of water out of the pool on Sunday to reduce our chlorine levels due to fresh fill water before opening Monday.
Do you think this will be enough water replacement / time to reduce our levels?
