Why the FRAG design?
Unlike a conventional reef aquarium, the INFINIA FRAG prioritises surface area rather than height. The 643 mm depth provides substantial front-to-back aquascaping space, while the 410 mm height allows stronger light penetration and makes it much easier to reach corals for placement, fragging and maintenance. Waterbox specifically positions the FRAG range for coral-focused systems and coral gardens.

Important: unlike the INFINIA Peninsula, the mesh lid is optional on the INFINIA FRAG, not included as standard.
Lighting, return pump, protein skimmer, heater and circulation pumps can then be selected separately according to the intended reef setup.
The INFINIA FRAG 125.4 is particularly suited to customers wanting an SPS-dominated reef, mixed coral garden or high-end frag/display system. Its unusual 122 × 64 × 41 cm proportions provide considerably more front-to-back aquascaping room than a typical 4-foot aquarium while keeping corals relatively close to the lighting.
