Oh, Boy! It's going to take a LOT of chlorine to clear out that sodium bromide. Doesn't it gunk up the filter as well, or is that only the Baq conversion that does that? As I remember, the S-B will kill algae and make the pool clear very fast (good), but getting the S-B out so it maintains FC levels is going to take as long and as much chlorine as it would have anyway (bad). Could be wrong about this.

If she can get 12.5% 5 gallon carboys it may be what's needed. And she MUST get a proper test kit--at least the WalMart HTH 6-way drop test kit, but preferably the K-2006.
