Thanks Evan. OK, according to Ben's post it sounds like the bromide can be removed with shocking on a sunny day, perhaps repeatedly. The organic form would have the organic part stick around and be hard to get rid of, but the Yellow Treat was just sodium bromide so didn't have the organic part. So that's good news.

So, smallpooldad, the fact that you were at high shock values after adding Yellow Treat probably means you got rid of most or all of your bromide, especially if your pool had exposure to sunlight. Wheh! That was a close call!
