Need some advice. Want to add more flow in my 120. Thinking about replacing my 2 koralia 4's with either 2 Vortech mp40ws, or a Tunze wavebox. I've seen videos on youtube for both, and they both seem to make pretty good waves. I've got some softies, lps and sps.
Here's what I've got now. 120 display with oceanic 3 sump, quiet one 4000 return to 2 overflows. Using 2 koralia 4's for additional flow, but I seem to have a lot of dead spots still. Want the wave action to clean up the dead spots. Asthetically, the Vortechs probably go unnoticed more, as the wave box sits right in the tank.
Another option is to add 2 more koralias and spend the extra grand that I save on a good 1/4 hp chiller, but don't really like the look of a tank filled with big powerheads.

Anybody using the vortechs? Is the flow that much more widely dispersed as the manufacturer claims?
