Micro Cube Tank | 32oz Desktop Aquarium

Dimensions: 4" x 4" x 8.5" T
 
The World's Smallest Reef Tank!
 
The Micro Cube is more than just a tiny tank, it’s a piece of PNW Custom history!
It was originally designed in 2020 during the early prototype phase of our now-iconic Micro Tank (40oz). We didn’t expect how much attention it would get. Despite being a prototype, the Micro Cube quickly gained popularity, earning its place as the world’s smallest running saltwater aquarium.
 
Because of its popularity, and because we love celebrating where we came from, we decided to bring it back. Don’t let the size fool you. The Micro Cube includes the same thoughtfully engineered accessories as our standard Micro Tank, making it fully reef-ready right out of the box. It comes complete with a dedicated light, return pump, filter media, and everything needed to support a living saltwater reef at an incredibly small scale.
 
Includes:
Display Tank + Stand: Sleek, low‑profile design showcases your aquascape at eye level.
3‑Compartment Sump Filtration: Mechanical, chemical, and biological filtration work in harmony to keep water crystal clear.
