Is this a light you've already purchased?
 
I would like to know this as well following
 
your light is a 46 watt light, for a 90 gallon you should have somewhere in the 150-200 watt range. Unfortunately that light won't successfully grow corals on your size tank. If your light is new, try to return it and search for something stronger, stay away from fluval lights.

Nicrew and Smatfarm are good quality low budget options.
