OM 4 way, wavebox or Vortech?

[banditpowdercoat]

OK, I am almost positive I am getting a 150g from a friend. He's got it plumbed right now with spraybars with plumbing over the top rim of the tank. I am not sure which way I want to go. OM 4 way, plumbed over the top, or up from bottom, Or a wavebox, or Vortech's??? I really would like to Not have powerheads. My 45g has a closed loop setup above the waterline, pointing down. But thers no random flow. Its all one direction...


Any help in which way I should go, would be greatfull. I wont have alot of time, when I get the tank, as its occupied and have to find temp accomodations for the livestock.
