I clean and disinfect 2 hot tubs. We use bromine. When draining/refilling or topping off we use non-chlorinated water. Today, I used a chlorinated water source (<1ppm) and the water turned amber... almost yellow, but more golden.
Is this what happens when chlorine and bromine mix?
Is there a reason why bromine is being used as a sanitizer? Is there a downside to changing over to chlorine?
