Red Sea Reefer 250 G2+, 54 Gal. Aquarium Kit, Black
The G2 Reefers come with new and improved water management, extra-fortified cabinets & aquariums, a REEF-SPEC ReefMat® ready sump, and extended warranty plans, and are available in a huge variety of sizes, to fit any space.
REEFER G2 systems are the ideal platform for the full “Red Sea Experience”, combining our LED lighting, wave pumps, dozers, and filtration devices into one smart eco-system operated via the ReefBeat App, and rooted in our 30 years of research on the needs of corals in artificial environments. In keeping with the REEFER concept, these systems still allow you complete freedom of choice to customize the tank with all your preferred equipment.
The G2 Plus now comes equipped with Red Sea's new Red Sea Reef ATO+ Upgrade Kit! - The ReefATO+ is an exceptionally reliable auto top-off system that includes a highly accurate temperature monitor plus an external leak detector and is supplied with a smart controller and useful ReefBeat features. It has a unique solid-state level sensor, with five titanium probes that can pinpoint if you are above, below, or at the desired water level, along with backup OFF sensors, a fail-safe mechanism that stops the pump if it is operating for too long, and of course ReefBeat notifications if anything is out of the ordinary.

Rimless ultra-clear glass
REEFER G2 aquariums are rimless, and constructed from ultra-clear, beveled-edge glass with increased thickness of up to 19 mm or 0.75”.
Extra fortified plywood cabinet
The marine-spec laminated cabinets follow the contour of the glass, and are now all fortified and made of plywood. The “floating tank” feature is now reinforced with front aluminum supports on all REEFER 625 G2 models and bigger.
Dual return pump outlets
All REEFER 350 G2 models and bigger now have dual side-facing return pump outlets, creating an even better water distribution.
Surface skimmer
The piping is hidden inside a large central overflow box, which has a large surface skimmer with removable comb parts, for easy cleaning.
Silent downflow system
The enlarged rectangular inlet to the downflow pipe reduces turbulence, making it easier to regulate.
Assembly-ready piping
All pipes are performed with quick connectors at all joints (no gluing required). Extra bulkhead connectors are available in both Metric and USA sizes for those that want to customize their sump piping.
High precision valve
All models now have a new and improved high-precision valve on the downflow pipe, allowing for easy regulation of the flow and a near-silent operation.
Professional REEF-SPEC sump
The professional sump includes a mechanical filtration media compartment (with micron filters & filter cups), which is easily removable, an optional refugium compartment, an adjustable height skimmer chamber for optimal skimmer performance, and a bubble trap to prevent air bubbles from returning to the aquarium.
ReefMat & Refugium
Plug & Play installation for ReefMat 500/1200, together with Refugium.
ReefMat & Reservoir
Plug & Play installation for ReefMat 500/1200, together with RO reservoir.
