HighlandReefer was nice enough to provide some excellent links and some good informative recommendations- you should read them.

If you have "a ton of zoas and sps" and you want to keep them alive for any length of time you need to be aware of the relationship between calcium, alkalinity and magnesium. These are the 3 things you'lll need to supplement as they're depleted by (hopefully) growing corals.
The first step is to purchase reliable calcium, alkalinity and magnesium test kits.
