Controllable DC Nano Skimmers, any out there???

[Joke]

As the title questions, are there any Controllable skimmers for nanos? I'm setting up a tank for a mate, and he loves controllable equipment. His tank is a custom 30g all in one and has a small skimmer chamber around 5.9 x 5.9 inches.
So, again, does anyone know of a protein skimmer that would fit the space, be sufficient at its job and is controllable?
So far I have found
-Tunze 9012 DC
-Tunze 9004 DC

I'm running a 9004 in my 25g. If putting in the sump, be mindful of the minimum depth on the skimmer. I could not provide enough water depth with the 9012 or the 9004. I opted for the smaller 9004 and placed it in the display.

The 9404 solves the minimum water depth issue.

True but wouldn't fit in my sump.

I prefer Comline equipment mounted in the tank as it was meant to be.
