Run system off of one pump

[BCOrchidGuy]

If you're keeping it all in one tank I'd go with 2-4 power heads, if you're running a sump, go with a mag 5 and two power heads. I asked about the SCWD and eveyrone told me the same thing, the stronger the pump the faster the motion, for wave action you want slow but lots of flow, I'd go with the natural wave power bar (I had one, worked great, will get another). That Mag 5 and two Maxi Jets on the naturalwave will give you tons of water movement.
