My new outdoor pool went into service on March 16th with bromine as the sanitizer. I've been getting advice from others to switch to chlorine. I like the bromine water and I am reluctant to switch. To do so means draining the pool or use sodium thiosulfate to neutralize the bromine. If not done, any chlorine introduced will only reactivate the bromine "in the bank". However, since bromine is not UV stabilized will it not deteriorate in short time if I don't add any more? If the bromine is so "ever lasting", why do I have to keep adding more? The "once a bromine pool, always a bromine pool" seems to be flawed. Otherwise, using chlorine to reactivate the bromine over and over may prove to make bromine less costly than it appears. Any comments on this will be appreciated.
