Joel, I can't tell you to be honest with you....I am still playing with the thing to get the single wave going. I don't have the frequency set correctly so I have a ripple effect right now.

I know that you do need additional directional flow, which I have, but from my understanding it takes the place of several pumps and eliminates the dead spots everywhere in the tank....

Just what I read, not from experience.....plus it really looks cool...LOL
