WATERBOX INFINIA PENINSULA 4820
Includes the aquarium, the cabinet, the sump and pre-fabricated plumbing.
EXPERIENCE INFINIA
With the Waterbox INFINIA Series, you don't just own an aquarium — you own a showcase of innovation, precision, and natural beauty. The INFINIA PENINSULA 4820 is designed in peninsula style to be admired from three sides, with a cabinet featuring double access doors. At 120 cm long with a 411-litre total volume, it is the perfect centrepiece for high-end marine or freshwater aquariums, where every angle reveals a spectacular reef or underwater landscape.
ULTRA-CLEAR GLASS
Built with ultra-clear (low iron) glass panels of 12 mm thickness, each aquarium is precision-bonded with high-strength silicone to ensure a secure, watertight seal that stands up to the immense pressure of a filled system. The Opti-white glass delivers a 91% transmittance, rendering the colours of your fish and corals with impressive fidelity, without the typical greenish tint of standard glass.
Glass overflow
Waterbox is the only brand to use black glass columns with the comb cut by water jet under pressure. The exclusive downflow technology keeps noise to a very low level, while the dual returns ensure efficient circulation throughout the aquarium.
Stabilizing mat
Every system includes a self-levelling mat that keeps the aquarium level on uneven surfaces and minimises surface tension on the glass, extending the lifespan of the system. Each aquarium is also laser-engraved with the Waterbox logo in the glass, proving authenticity.
QUIET, SIMPLE, RELIABLE PLUMBING
The INFINIA PENINSULA 4820 comes equipped with a meticulously designed, pre-glued and pre-measured plumbing kit, ensuring hassle-free installation and leak-free performance.
