Calcium Chloride & Soda Ash

[scherzo]

Just doing some google research and there seems t be some concern with Bromide content in the Dow flake. Hey apparently made the change back in 2007ish?

Anyway. I'll keep doing more research.

Yeah I thought the days of Dowflake were over unless somebody still had some if the old stuff.

I use Randy's DIY two-part using baking soda and Kent Turbo Calcium.

I used to use the Dow brands but eventually had some issues. I later read somewhere it is only guaranteed to be 37% pure calcium clhoride. I would go with BRS or Fauna Marin brands, much cleaner with no residue to speak of.

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

It is 87%

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.
