What’s in the box · standard with every all in one aquarium

All in One

Built-in Filter

The filter is built right into the back of the all in one aquarium. Water skims off the surface, flows through the filter media hidden behind the black rear wall, and is pumped back into the display. No sump, no hang-on box, nothing to plumb.

Clean

Filter Media

Filter media comes standard with every all in one tank. Mechanical, biological, and chemical filtration designed to keep your nano tank water sparkling.

Laser Cut

Precision

Precision-made gear to keep your media in place. Laser-cut premium acrylic for a flawless, exacting fit. We obsess over the parts you’ll rarely think about.
