Waterbox INFINIA FRAG 175.6 – Premium 6ft Shallow Reef & Coral Aquarium System + furniture
The Waterbox INFINIA FRAG 175.6 is the largest model in the current INFINIA FRAG range, providing a huge 1.84 × 0.64 m coral display footprint while retaining the shallow 410 mm height that defines the FRAG series.

Why the FRAG Design?
The INFINIA FRAG prioritises usable surface area rather than aquarium height. At only 410 mm tall, reaching the bottom of the aquarium for coral placement, fragging, cleaning and maintenance is considerably easier than with a conventional deep reef aquarium.
The shallow design also allows reef lighting to reach corals efficiently, while the generous 643 mm front-to-back depth provides plenty of room for open aquascaping and large mature coral colonies.
Key Features:
Ultra-clear rimless glass construction
Massive 1836 × 643 mm aquascaping footprint
Shallow 410 mm display specifically suited to coral-focused systems
Centralised glass overflow with dual adjustable returns
Stabilising aquarium mat
Pre-engineered Quick Connect plumbing
Precision gate valve for quiet and stable overflow operation
Integrated return-line check valve to help prevent backflow during pump shutdown or power failure

MARINESHIELD Cabinet:
The INFINIA FRAG 175.6 uses Waterbox's premium MARINESHIELD aluminium-frame cabinet. The rigid aluminium framework provides excellent structural strength while resisting warping and the demanding humid environment associated with large marine aquariums.
Moisture-resistant PET-laminated panels and doors provide the external finish.
Available cabinet colours: Black or White.

Lighting, return pump, protein skimmer, heater and circulation pumps can be selected separately according to the intended reef setup.
The INFINIA FRAG 175.6 is particularly suited to a large SPS reef, LPS coral garden, mixed reef or professional coral display. Its 6-foot length combined with 64 cm depth provides an exceptional amount of coral-growing area, while the shallow 41 cm height keeps even a system of this size easy to access and maintain.
