Sorry WetWhistle - I disagree.
The reason I suggested the stock I did is that those can survive for quite a while in very low nutrient water - ultil the feedings of fish and their resultant waste provide sufficient nutrients for them to thrive.
Its actually better not to wait, By delaying the introduction of desirable livestock - meaning corals, nems and clams, into the system all your doing is opening the door to algaes and other organisms that you don't want.
Many of the problems new tanks face are the result of the build-up of unconsumed and unbalanced nutrients. Corals, Nems and clams prevent this. People forget that their corals are, or should be a major component of denitrification and nutrient sequestration. There is nothing to be gained by allowing algae and cyano to occupy these nutrient niches before coral.
Small clams have nutrient requirements which require an established tank - large clams are fine - provided you introduce fish with them. Small nems will grow to take up excess nutrients - same with fleshy LPS - place these in the detritus drop points of the system.
Snails - trocus - should go in as well - I would stay away from all crabs in a new system -
The only testing I would recommend at this point is ammonia, salinity and temperature - and an occasional nitrate test - as your nitrate goes up - add more corals.
A too clean of system is more forgiving to mistakes than a dirty one, and a stocked system will be more resistant to those early nuisance colonizers than an empty one.
I know I'm going against conventional wisdom with this advice...I seriously doubt many here have ever tried the approach I have recommended. But I assure you - it works and it is actually faster and easier to get the results you want following this approach.
