New to salt water

[Myka]

BlueTang has good advice. Although I would still test the big three with those LPS in there. H2Ocean is a good salt, and the parameters seem to be fairly reliable (some people have noted low magnesium though). Buying a high quality salt like that will often dismiss the need for supplementing provided the salt isn't lacking, and regular water changes are performed. Test every new bucket before use, and supplement the freshly mixed saltwater as needed.

If you take a read through the "My tanks" link in my signature you will find an article about calcium, alkalinity, and magnesium as well as doing proper water changes (in the novice article I think). Those articles are easy reading, and have lots of basic info.
