I just set up a 55 gallon aquarium. I have an xp4 filtering it. The spraybar helps with surface agitation on one half of the tank, but the other side is pretty still on the surface. I don't want to strong a flow that would push my fish all over the place. I'm not really that well versed on what powerhead to use or placement. I'd prefer to use a maxi jet or koralia. I have a green sunfish about 5 inches, 3 cichlids about 5 inches and 2 3 inch striped raphael catfish. The cichlids are only temporary until I get a new big tank for them, since my 210 gallon I had them in broke. Thanks.
