It appears that Dow is changing the process by which they produce Dow Flake and may now contain a much higher level of Bromine.
Here (http://reefcentral.com/forums/showthread.php?threadid=1271282&perpage=25&pagenumber=1) is the thread from RC in the Chemistry section.
And I just bough a 44kg bag last week and was considering selling my CA reactor and just use this stuff.

I believe it is bromide.
The latest stuff I got (food grade Calcium chloride) has a manufacture date of 2004, thus ruling out the elevated levels.
I don't know if I wil be able to get more or not.
I would hope that in time someone finds a good new source.

TTBOMK DOW flake calcium (food grade) is OK if you have stuff that was manufactured before the increased bromide date. I have not seen anything that indicates that all DOW flake is OK.
