powerhead recommendation wanted

[thewebhead]

I'm setting up a new FOWLR system for a 47g tall (20x18x30h) and have a ViaAqua Multi-Skimmer @ 200gph coming, but assume I'll need additional circulation and am looking at a maxijet. A Model 600 @160gph would get me about 7.5x turnover total, and I've read it should be 6-10x... Should 1 jet be okay or should I try 2 600's or 1 Model 900 (230gph) instead?

You need to factor in your skimmer's turnover as well as that will help you out in the end.
I prefer using two powerheads rather than one large 900.
Not only are they more energy efficient in the end, moving the water around the tank without having dead spots seems to be easier for me.
