I use Seachem, but I'll probably switch to one of the suggested brands of epsom salts. When I originally bought the vat-sized container of Seachem, I wasn't aware that epsom was usable since I assumed it wasn't food grade as it's not designed for ingestion (that I know of).

so I guess just any epsom salt will work huh
I wouldn't assume that. I haven't researched it, but I would say that since it isn't food-grade, not all brands may be created equal.

There is some really good info on this subject over at Reef Central, in the reef chemistry forum, Randy has quite alot of info there... I am in the process of mixing his recipe for a 3 part calcuim additive, Magnesium being the 3rd part... His recipe calls for epsom salts...

The use of Epsom salts....MgSO4....will eventually cause a sulfate imbalance in the tank and isn't a good idea. It is better to use MgCl2....which in bulk is either Magflake or Nigari. Randy suggests only using Epsom salts no more than within a 6 to 1 ratio....6 parts MgCl2 to 1 part MgSO4.

so I've been dosing the epsom salts, the only issue with it is yes over time it will build up something, dont remember what I read. But as stated in the article, if regular water changes are done, which mine are done weekly, there will be no issues.
