Bulkhead size for 30 gallon

I have just purchased a 30 gallon glass aquarium - 24 x 18 x 18. It's still at the lfs as I want it drilled. I am considering putting a 30 g sump on this.

I have a couple of pumps lying around from past tanks including a Oceanrunner 3500 and was considering using this as the return pump with a manifold going back over the top. For this I figure a 1.5" bulkhead, which I intend to run through one of the short sides.

I intend on keeping lps (Elegance corals here in Australia are great) with a rubble bottom and 3 or 4 small fish (1 or 2 blue assessors, bicolour blenny, maybe a Bangaii or 6 line wrasse).

Is this pump going to be too much for the aquarium or the sump? Do I need this much flow for an lps dominated aquarium?
 
Nope, actually it would probably be fine. You can never have enough water flow. If it seems to much you can always throttle it back with a valve.
