Magnesium makes the calcium available for the corals to use. You want a Mg level roughly 3x the Calcium level. Therefore, if you want 450ppm Ca, you want 1350ppm Mg.

does it also help in the growth of the corals?

It is needed for the corals to be able to grow, yes, also for Coraline algae.

Bulk Reef Supply supplement is the best value, but a number of manufacturers make additives, Seachem, Kent, etc.

List what you are dosing. A lot of people dose useless stuff and don't dose the essentials.

that was roughly 2 wks ago. i dose calcium about every other week or so. just to try to stay on top of it. i have two clams that i was told will use a lot of the calcium. the lowest ive seen it drop to is 320.

I have a 40B, so I don't have a large need for dosing, so I use the aquavitro line. I currnet;y dose the calcification, vibrance for iodide, ions for mag., and of course fuel. I don't have to add a lot, because I DO change water every so often....if you have a large tank, then the BRS stuff is definately the way to go, as the aquavitro line can get expensive....:doh:
