I am hoping that someone could explain the "once a bromine pool, always a bromine pool" adage a little further.
An indoor pool, drained one week ago and re-balanced. Bromine tablets are dissolving in a commercial-grade chemical dispenser. However, the bromide salts used to create a "bromine reserve" were not used.
My (very limited) understanding of traditional practice is that switching to salt/chlorine for sanitation would require draining the pool, because any chlorine generated by the cell would be converted to bromine.
1) Is that true?
2) If so, what is the downside to switching to salt/chlorine and having the chlorine that is generated converted to bromine?
Basically, do you really need to drain said indoor pool before converting from bromine tablets to a salt system?
