BBB Fan with mustard algae in Intex pool

[Watermom]

Please do not use the sodium bromide. It will create a chlorine demand that will be very hard to overcome.

She already did ............

I have asked Ben to pop in on this thread when he is able.

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.

@ Carl, WM: sodium bromide is converted to free bromine when you add a chlorine source, such as bleach. Ammonium chloride is the other "Yellow X" product; it combines with chlorine to form monochloramine. You have to destroy monochloramine before swimming, but you can swim in brominated pools just fine. The problem is, you cannot 'stabilize' the chlorine (bromine!) loss, so usage is very high.

@ All: the mustard treat thread is here: http://www.poolforum.com/pf2/showthread.php/25757

"Stop Yellow" appears to be a Pinch-a-Penny product of the ammonia variety.

I KNEW there was a reason not to add bromine to a chlorine pool.....
