What does everyone test for in reef?

[trish&dave]

There are SO many additives available out there, and I know you are not supposed to add anything you cannot test for, so my main question is, in a reef tank, what are the essential items that need to be tested? Currently we have: Ammonia, NO2, NO3, PO4, alkaline, PH, and calcium.
