Need some advice on if i should make a spray bar from 1/2" pvc or use a nozzle. The back of the tank is spray painted black so either one should blend right in. Got a crazy stupid return pump (up to 620 gph) so it shouldnt have a problem with a spray bar that is like, 2-3 ft long. The sump is fed from a drilled overflow... Would like some advice before tomorrow. Any cons to having a spray bar in the refugium?
