Red Sea Max Nano G2 XL Aquarium

The Red Sea MAX NANO G2 XL is an all-in-one reef aquarium with an integrated rear filtration compartment. It provides a 125 litre total system volume and a larger aquascaping footprint than the MAX NANO Cube, while keeping equipment behind the display.

The XL's rear sump accommodates mechanical filtration, a dedicated protein skimmer, media space and the return pump. Its standard top-off reservoir supports day-to-day water-level management. The sump is also designed to accept NanoMat and ReefATO+ upgrades, which are separate accessories.

Plan access behind and above the tank for cleaning the skimmer, changing filter media and refilling the reservoir. Confirm the selected package's cabinet and lighting configuration when planning the installation. The built-in equipment simplifies component layout, but the reef still requires cycling, water testing, a suitable heater and stocking matched to its available swimming space.
