Red Sea REEFER MAX 425 G3 Aquarium System (91 Gal)
The Red Sea REEFER MAX 425 G3 is a complete, ready-to-run reef aquarium system built around a rimless ultra-clear glass display, a marine-spec cabinet, and Red Sea's full suite of G3 hardware, all managed from the ReefBeat app. With a 90.6 gallon display and a 114.4 gallon total volume on a deep 23.6 inch front-to-back footprint, the 425 gives serious reefers the width and water volume to build an impressive mixed or SPS reef while every pump, skimmer, and roller stays hidden below.

Frequently Asked Questions
Is this really plug-and-play?
Yes. The 425 G3 ships with the pump, skimmer, powerheads, filter roller, ATO, and lighting matched to the system. You assemble the cabinet and tank, connect the pre-glued plumbing, add rock, salt, and water, and configure everything through the ReefBeat app.
How is it different from the REEFER MAX 350 G3?
The 425 is a deeper, larger-volume tank: 90.6 gallons on a 23.6 inch front-to-back footprint versus 72.1 gallons on the narrower 350. To move the extra water the 425 steps up to stronger 2x ReefWave 45 circulation pumps (versus the ReefWave 25 on the 350) and adds a larger 24 gallon sump, while both share the same REEFER DC 600 skimmer, ReefRun G2 6000 return pump, 2x ReefLED G2 115 lighting, and ReefMat 500 roller.
Can I pick it up in store?
