Vortech vs Tunze

[ed99]

Folks,

Despite all the good advice I had about closed loop systems, space and access to the tank has pushed me to use powerheads in my tank instead. So now I'm thinking of using a couple of Vortechs or Tunzes (6100s) on a controller.

While it looks like people haved had good experience with both, I like the idea of the Vortech because the motor is outside of the water. However my tank has two viewing sides (pic below) and therefore I want to put the second pump on the back pane. Does anybody have any comments on how that would work with Vortechs (i.e would it limit its ability to generate waves and create chaotic flow), or am I better off using a Tunze because of its swivel capability.

Appreciate any comments.
