Reef supplements: what to buy for a friend?

[stupid_naso]

Well guys, my friend's birthday is coming up. She just started adding corals to her tank and she is interested in dosing supplements to her tank. So what are the most beneficial supplements I should get for her? My friend and I are planning to get her a set of beneficial supplements.
I was thinking Calcium, Strontium and Iodine. Anything else? I have used CoralVite in the past, and also MicroVert. I don't think MicroVert is beneficial. I've been looking for DTs but I cannot seem to find them at any of my LFS. If you know a website where I can get it, let me know.
Thanks,

I would get her a good book, and a large container of kalkwasser, you dont need much else HTH

I second that notion.
