Choosing the right aquarium is one of the most important decisions any marine hobbyist will make. From the quality of the glass and cabinetry to the design of the overflow, sump and filtration, every detail contributes to the long-term success of a reef aquarium.
This is exactly where Neptunian Cube has made its name.
Developed by a team of passionate reef keepers, Neptunian Cube has spent more than a decade designing premium marine aquarium systems that combine elegant aesthetics with practical engineering. Every aquarium is created with the goal of making reef keeping simpler, cleaner and more enjoyable, without compromising on quality or performance. Today, the brand is recognised worldwide for its beautifully crafted reef systems, innovative filtration designs and attention to detail.
Built by Reef Keepers, for Reef Keepers
Unlike many aquarium manufacturers, Neptunian Cube designs its systems around the real needs of marine aquarists. Every cabinet, sump and overflow has been carefully considered to improve accessibility, maximise filtration and simplify maintenance.
The company manufactures a wide range of professional reef systems, all featuring premium low-iron (Optiwhite) glass, precision silicone work, aluminium-framed cabinetry and intelligently designed filtration compartments. The result is an aquarium that looks exceptional while delivering the performance expected by serious reef keepers.
The Magic Pro (M-Pro) Series
The flagship Magic Pro (M-Pro) Series represents Neptunian Cube's most advanced reef aquarium system to date.
Designed specifically for marine aquariums, the M-Pro Series combines minimalist styling with innovative engineering to create a complete reef-ready system. One of its most distinctive features is its ultra-slim integrated overflow system—described by the manufacturer as the world's thinnest weir box. By integrating the overflow and concealing the plumbing through the base of the aquarium, the M-Pro maximises usable display space while maintaining an exceptionally clean appearance.
Each M-Pro aquarium includes a purpose-built sump featuring dedicated chambers for mechanical filtration, protein skimmers, reactors and return pumps, alongside practical additions such as probe holders, dosing tube guides, an integrated top-off reservoir and an electrical compartment. Adjustable baffles also allow hobbyists to customise the filtration layout to suit their preferred equipment.
Available in a range of sizes, the M-Pro Series provides an outstanding foundation for everything from mixed reefs to SPS-dominated showcase aquariums.

The Desktop (T) Series
Not every marine aquarium needs to dominate an entire room.
The Desktop (T) Series has been designed for hobbyists looking to create a stunning nano reef without sacrificing quality or functionality.
Ideal for offices, bedrooms, apartments or smaller living spaces, these compact systems feature the same premium build quality that Neptunian Cube is known for. Each aquarium includes an integrated rear filtration system with dedicated filtration chambers, allowing users to create a clean and uncluttered display without the need for an external sump.
Constructed from high-quality low-iron glass with beautifully finished silicone joints and practical maintenance features, the Desktop Series provides an excellent platform for nano reefs, shrimp aquariums or carefully aquascaped freshwater displays.
For retailers, the Desktop range also represents an excellent entry point into the Neptunian Cube brand, offering premium design at an accessible price point.
