Red Sea REEFER MAX 750 G3+ Aquarium System (158 Gal)

The Red Sea REEFER MAX 750 G3+ is a complete, plug-and-play reef system: a eurobraced, ultra-clear glass reef aquarium, a marine-spec cabinet, a sump, and Red Sea's matched lighting, filtration, circulation and monitoring, all run from the ReefBeat app. It holds 158.5 gallons in the display and 198.1 gallons in total. New for the G3+ generation, every REEFER MAX now ships with the ReefControl Pro controller, a ReefSense pH/Temp probe and the ATO Module.

What's New in G3+

• Redesigned flow system that Red Sea rates at up to 50% more water circulation
• ReefGate high-precision gate valve on the downflow pipe for easy flow adjustment and near-silent operation

Frequently Asked Questions

Is this really plug-and-play?
Yes. The REEFER MAX 750 G3+ comes with lighting, skimmer, return pump, wave pumps, filter roller, controller and ATO matched to the system. You assemble the cabinet and tank, connect the plumbing, add rock, salt and water, and set everything up in the ReefBeat app.

How is it different from the REEFER 750 G3+?
It is the same aquarium, cabinet and sump. The REEFER 750 G3+ leaves out the lighting, skimmer, return pump, wave pumps, ReefMat and pH probe so you can pick your own gear, and it comes with the ReefControl Pro controller.

What changed from the G3?
The G3+ adds the ReefControl controller and ATO Module, a redesigned flow system, the ReefGate gate valve on the downflow, a larger rectangular downflow inlet for quieter running, and a removable surface skimmer in the overflow.
