You could get some of the loc line fittings that has the wide narrow nozzle for the return inside the tank. Lots of options there for directing the return flow and make it look nicer. As long as the nozzles are near the surface so you don't get too much back siphon when pump is off you will be good to go!It’s about $20 more so maybe I will just go with 400 gph plus less room taken up in my tank. I’m not counting on the jet to do much at all just thought it would look better then a piece of pipe. 2- 480gph power heads one in bottom left angled up and one top right angled slightly down will be plenty correct? I will be using about 2” of sand
Should be good with the 2 power heads plus the return flow.
