Keep in mind that the process that Dow now uses to make the various calcium chloride formulations no longer includes a step to bring down the bromine (in the form of bromide) levels, so while it's probably still okay for occasional use, I'm not sure I'd attempt to use a homemade two-part solution for a tank with very heavy calcium and alkalinity demands.

How much are you planning to dose?Years ago we'd make Randy Holmes-Farley's two part solution, and the calcium part would just be Dowflake dissolved in RO/DI water.
If I recall correctly, Dowflake is no more.
What do people use now for the calcium part?
I have a calcium reactor but have a few BRS 2 part kits on hand in case I need to add a little here and there. Its pretty inexpensive, not as cheap as dowflake was but not bad
