FAQ

Is this a complete system?
Yes. The MAX package includes the tank, cabinet, sump, plumbing, two ReefLED G2 lights, DC skimmer, two ReefWave pumps, ReefRun return pump, ReefMat filter roller, and ReefATO+, all app-controlled. Add salt, sand, rock, and livestock and you are reefing.

Why two lights and two pumps?
The 250 has a longer, wider display, so it ships with two ReefLED G2 115 lights and two ReefWave 25 pumps for even light and flow from end to end.

Freshwater or saltwater?
Saltwater and reef only. The ReefMat and ReefATO+ are not compatible with freshwater setups.

What are the display dimensions?
The display tank is 35.4 in x 19.7 in x 20.9 in (53.6 gallons), and the total system stands 55.1 in tall.

How does the warranty work?
Every REEFER G3 includes a 3-year warranty, plus 2 more years when you register your system with Red Sea within 90 days of purchase.
