Red Sea REEFER MAX 425 G3 Aquarium System (91 Gallons)

$6,398.99
⚠️ Not included with any Red Sea package

Red Sea aquarium packages never include the dosing pump (ReefDose 2 or 4), the dosing tubing & accessories, or the ATO reservoir (the ReefATO+ unit itself is included). We recommend adding these with your tank so everything arrives together:

Red Sea REEFER MAX 425 G3 aquarium system. 91 gallon display, full REEF-SPEC equipment package pre-installed.

Equipment and dry goods ship at their own rate. Free shipping over $399 applies to live corals, fish, inverts and copepods, so this item does not count toward that threshold. Your shipping is calculated at checkout from our configured dry-goods carrier rates.

We ship within the continental US. Alaska needs a shipping quote before you order, and we cannot ship to Hawaii — get in touch first.

Description

The Red Sea REEFER MAX 425 G3 takes the REEFER G3 platform and adds Red Sea’s full REEF-SPEC equipment package on top, so the aquarium arrives ready to run rather than waiting on separately purchased filtration and lighting.

  • Display Tank Volume: 91 Gallons
  • Glass: Ultra-clear, beveled-edge rimless glass with a low-profile overflow
  • Cabinet: Marine-spec laminated cabinet, available in black or white
  • Filtration: REEFER DC protein skimmer and ReefMat fleece roller filter pre-installed in the sump
  • Circulation: ReefWave DC pump(s) pre-installed and matched to tank volume
  • Included: ReefATO+ auto top-off, temperature monitor, and leak detector, all tied into the ReefBeat app
  • Warranty: 5-Year Manufacturer Warranty (3 years standard + 2 years upon registration)

Every piece of equipment in the REEFER MAX package is matched to the tank’s volume at the factory, so circulation, skimming, and top-off are all correctly sized from day one rather than left to guesswork.

We are an authorized Red Sea dealer and can order any REEFER MAX G3 configuration directly. See the full official spec sheet on Red Sea’s website.

Shipping & Returns

  • Equipment and dry goods ship at their own rate. Free shipping over $399 applies to livestock only — corals, fish, inverts and live copepods. The $15 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
  • All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
  • Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
  • Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
