Looks like EZTank.com is also Aquaricare.com and SurgArium.com. I pulled the patents on this one a while back thru the US Patent and Trademark Office website while I was reviewing Adey's patents along w/ the Eco-Wheel patents to see what exactly was patented and what wasn't patented in regards to their ATS designs. Here are the patent numbers that I pulled from the USP&TO website for those inquisitive minds that like to look up this kind of stuff (I looked up Mark Reinke, the inventor on the USP&TO website):
ATS: #5,536,398
Surge: #5,738,137
If you want to see the full patent including all pictures and diagrams in the patent, you will need to install the AlternaTIFF plugin for IE and then click on the IMAGES button after looking up the patent:

Here's a pic of the Aquaricare / EZTank ATS from their website:
And here's the URL where you can download their information packet (they're pretty large files for us users on dialup

The EZTank ATS unit looks like someone could easily DIY it as it basically is nothing more than a trough lit with NO's and it has bulkheads on both ends along with baffles across the width of the tank and these baffles are spaced every couple inches down the trough. There's also some eggcrate material underneath the baffles to make a sort of "refuge" for critters. I'm not sure that's wise as pods can dessimate an ATS screen if left unattended, but apparently the design works for the author if maintaned properly (I'm speculating here).
The surge is a glorified Carlson surge with a twist. The twist that they did with their design is that it looks like they've taken the output from the surge and had it dump into a second container before it surges into the tank. I think this might minimize the bubbles, etc. I'm going to have to read thru this one further... FWIW, I think someone could prove prior art on this design...
Enjoy the reading!
FWIW, If you really want to read up on the ATS concept, get Walter Adey's Dynamic Aquaria 2nd Edition book. It blows that EZTank propaganda out of the water.
