Not having success with BBB in my hot tub

[chem geek]

On a sidenote, I have to empty my softtub soon, would it be ok to empty the 300 gallons into the pool??? The pool holds approx 14,500 gallons and is an SWG pool. The softtub is bromine, is there the potential for a chemical problem???

You should not empty your softtub water into your pool because you NEVER want to add bromine to a chlorine system. The reason is that hypobromous acid (analgous to hypochloric acid) will turn into bromide (analogous to chloride) when it disinfects or oxidizes items in your pool and the chlorine (hypochloric acid) will then convert the bromide back to hypobromous acid thus reactivating it, but the chlorine gets consumed (turns into chloride ion) when this occurs. Hypobromous acid is a less effective disinfectant and oxidizer than hypochloric acid so the net effect is that you replace some of your chlorine in your pool with a less effective sanitizer and you can never get rid of this bromine (except by drain and refill).

Essentially, once a bromine pool, always a bromine pool.
