Reef tank additives?

[MikeP]

What are the nessecary additives to have for a reef tank. I want to place an order at J&L so I figured I would buy a few things at once to save on shipping. When I get the tank going I will not have all the bells and whistles. My equiptment will be sump, skimmer, fuge, return pump and powerheads. So I'm sure I will need to 'dose' with some addidtives I just don't know which ones.

Thanks

Calcium and carbonate are the two big ones.

BTW, I price match.

Check out the ChemMaster forum for Ca, kH, and Mg additives. Randy Holmes-Farley's 3 part is the best, and cheapest way to go.
