Anyway. I'll keep doing more research.

Randy doesn't see a problem with the bromine as long as regular WC are being done.

The Calcium Chloride I use and also sell as Coral Grow Ca (http://www.oceanfreshaquarium.com/coral-grow-ca/)
is high purity anhydrous guaranteed over 95% Ca and I test every batch for Bromide content.
