Check out the Chemaster's (http://www.canreef.com/vbulletin/forumdisplay.php?f=67) products. I have ordered from him a few times. Good product and good prices.

Have you tested your mixed IO salt water for Ca and Mg? What are the numbers? What do you want them to be?

I use his products. Follow his mixing amounts also, which I think are based on Randy,s writings from RC.

do find the numbers vary a bit pail to pail so I'll get my amounts from this calculator (http://reef.diesyst.com/flashcalc/flashcalc.html), target here (NSW (http://www.reefkeeping.com/issues/2004-05/rhf/index.php))

I also use littlesilvermax's stuff

Most people just use generic no-name pharmaceutical grade calcium chloride and a mix of magnesium sulfate and magnesium chloride. ChemMaster, Bulk Reef Supply, Ocean Aquatics and Oceanic Corals along with numerous others sell them these days.
