An Eheim Professional II Aquarium Canister Filter next to a waterproof "Otterbox" 8000 specs on the otterbox can be viewed here. http://www.otterbox.com/products/otterbox/pdf/8000_webDrawing.PDF
Front view of the Eheim filter next to the Otterbox. When I saw the otterbox, it just seemed like a natural fit to turn it into a canister filter for nano tanks
Close up of the otterbox. The hinge is on the left side, with the closing latch on the right side. There is a waterproof O ring that runs petween the body and the lid.
This is the submersible pump that was secured into the lid of the otterbox. It's a six volt pump with adjustable flow that will move about 50 gallons an hour at max flow. For the Nano tank that I am using it with, I've lowered that to about 10 GPH.
Suction cups on the back of the pump
The company that makes the pump is called Skyish. Their Web site is at http://skyish-zs.com/english/encompany.html
The model number is the TP-180. I did a lot of looking around and I would highly recommend this manufacturer.
This is a close up of the flow adjustment on the TP-180. This particular model is made to run on 6 volts, but they make an identical model that runs on 120V. I asked for the 6volt so that the canister can be run on a battery pack or a small 6V solar panel.
This is the Nano tank canister filter shortly after being completed.
1/4" clear down tubes. running from the filter to the tank. This particular tank hold about 3/4 of a gallon and is a natural tank.
Wider shot of the canister, the tubes and the 6 volt power line running from the Skyish TP-180 pump which is mounted in the lid with waterproof marine epoxy.

Back view with latch open
Front view of filter with latch assembly open.
Lid assembly showing the waterproof O-ring, the skyish submersible pump, the 1/4" flexible intake tube and the power cord which is sealed on exterior and the interior with marine epoxy. The white discoloration is the adhesive that was used to hold the insulation lining inside the otterbox 8000. I did not feel that the insulation was necessary and by removing it, the interior filter capacity was increased as well.
Interior view of the filter. The 1/4" ID flexible tube is the intake. It forces the water to the bottom of the filter so that it has to pass up through the filter medium before it is pumped out by the skyish pump that is mounted in the lid. The pump is connected to the intake and the lid by marine epoxy.
Front view of canister filter. Intake is on left and outflow on right. Both are 1/4" OD. and sealed into the canister with marine epoxy.
Side view showing latch on canister filter. Power cord in on the left. Intake and outflow are on top.
The maximum flow rate for this pump, with no head is about 45 to 50 gph for the skyish 6v submersible pump. If you wanted to place the filter on the floor with a Nano tank on a table (using a shorter 1/4" hose than I have here) It could probably move about 20gph.
