I'm doing a CL system and wonder if I need 3/4 or 1/2 for CL outlets? useing a hammerhead pump with 12 returns outlets on a 180g tank.

Gotta figure out your friction loss. A complete piping diagram with lengths of piping in system would help answer your question. Also with 12 outlets you will have to engineer size of pvc throughout system a bit more. Shoot from hip and is 12 1/2" will give you the potential for about 10000GPH so 1/2" would work and give better velocity for more random, turbulent flow.
