New to the forum...Here's my setup. Can I get some pointers??

I have one circ pump in the corner that blows over the heater to disperse the heat well.
The main filter return has some good output and is pointing somewhat down and In the middle of the tank. maybe one more circ pump?

 

what types of corals are you interested in keeping? that will help clarify your lighting and power head needs. In terms of bulbs, people usually recommend ATI or geissman as quality T5 bulbs.

I would say you would want at least two (one on each end) good powerheads - it helps keep your water moving, detritus suspended to be removed, and fish/corals enjoy the movement.
