, even with a big pump, you will need some supplimental flow. You could look into a SCWD or maybe a sea swirl to help with uneven water flow. Maybe even add a spray bar. These will has add head pressure.
You want chaotic flow for a reef and one nozzle is not going to cut it. Too much pressure might make it hard to keep things in place ... ie sand.
A couple of power heads on a wave timer will do nicely and don't really add noise.
