Like the person before, we have also converted our indoor pool from Bromine to salt water, along with our indoor hot tubs. Our reason for converting was that we had homeowners who were complaining that the Bromine was breaking them out. We completed the conversion three months ago, and we were told at the time that we did not have to drain the pool for the conversion; however, some of the homeowners still think there is Bromine in the pool. Will Bromine leach out of the concrete walls of the pool, and if so, is there a time frame where this will stop? Volume on this pool is 27,169 gallons. I appreciate your advice and information.
