"....bromates are a suspected carcinogen."
Did some research on this. Appears this statement is true and the body of evidence in support of this statement is growing rapidly.
So no bromine for me.....
On a realted note: It concerns me that there is a manufacturer out there of ozone equipment that actually recommends the addition of sodium bromide to the pool water in conjunction with the use of their ozone and ionizer equipment.
