Additives?

[fubr]

I was wondering what exactly(product names,type, etc) I should add into my tank.
*Recap of my tank*-30gals,20pounds LR, 1 domino damsel, 4 anemones(I believe them to be rock anemones/Aiptasia spp.), 4 turbo snails and a billion other little snails and slugs.
Now I hear calcium is good to add, and coral-vite or something like that?
Any help would be appreciated.
Also my Red Slime is almost gone...Hoo rah!

Wow thanks for the quick reply!
This may sound liek a dumb question but what do they do?
I never looked into additives, thats why I may have many questions.

Thank you guys for all the replies!
Clownfish: I was looking through out that site and I kinda liked the ecosystem 40. The only problem is they dont have any type of pricing anywhere on their site. Is that what you got? How much did you pay for it?
