Red Sea REEFER 250 G3 Deluxe - Sumped Reef System w/ ReefLED 115 (x2) & Arms

Reinforced ultra-clear glass

REEFER G3s are constructed from ultra-clear glass with increased thickness of up to 19 mm/0.75”. REEFER model 425 and above are eurobraced for extra strength, while the smaller models are rimless with smooth, beveled edges.


Silent downflow system

The enlarged rectangular inlet to the downflow pipe reduces turbulence, resulting in a quieter operation.

Optimized water circulation

REEFER G3s feature a fully redesigned flow system, delivering up to 50% more water circulation. The larger models also have wider return piping and upgraded nozzles to further maximize flow.

High precision gate flow valve

All REEFER G3s benefit from the new ReefGate, high-precision bespoke gate valve on the downflow pipe, allowing for easy regulation of the flow and a near silent operation.

Improved return outlets & overflow box

The central overflow box is fitted with a removable surface skimmer for easy maintenance, and the return outlets on all models have been curved for improved water distribution.

ReefMat-ready

REEFER G3 systems have a removable, ReefMat-ready mechanical filtration compartment, complete with micron filter socks and media cups.

ReefATO+

All REEFER G3 models come with the ReefATO+ system, which keeps your water volume and salinity stable, and includes an accurate temperature monitor as well as a highly sensitive leak detector.
