It says "wave-like flow", but I wonder what that means, exactly!

They're really nice units. At the time they were first introduced to the hobby they were claimed to beat Tunzes in cost but in the end that's not really the case. But they are pretty slick units. For one there is no electrical part in the water. And with the controller they can create some serious flow patterns. There were demo videos from about a year ago, here check out this one from melevsreef, http://www.reefcast.com/episodes/reefcast15.mpg

The only real drawback to me that I see, it has to sit square on the glass so that limits your placement options and you can't rotate it to be at an angle to the glass like you can with a Tunze.

Otherwise though they are pretty darn slick little units!

Thats a crazy video! I could find a way to make that work in my tank. I emailed the tech guys from the manufacturer's website, and he said the controller would be available "this summer". I'm going to look into this one some more.

I guess the one in the video was run by a prototype controller, so the real controllers will be out this summer.

I run one of the EcoTech Marine VorTech pumps in my system and want another. The manufacturer really stands behind their warranty too. Initially the newer units had a defective teflon bearing which they promptly replaced. I only run it during the daytime hours. It creates some great current that the corals love and the fish like to ride too. The only negative that I have found is that the odd time a snail or star fish find themselves caught inside when the unit powers up in the morning. The controllers are supposed to be out soon.

Where did you get yours from?

I purchased mine new from a guy on Reef Central over a year ago now. Several Canadian retailers now offer them. Hidden Reef & Ocean Aquatics are a couple of them, but I am sure that other vendors on this board sell these too.
