Red Sea Reefer G2+ 900 Aquarium

Red Sea Reefer G2+ 900 Aquarium is designed for hobbyists to create and manage their ideal reef tank using preferred hardware and advanced water management systems.

The REEFER G2+ series of reef-ready aquarium systems comes in a huge variety of sizes, includes top-of-the-line infrastructure, filtration, water management and the ReefATO+ system. It is designed to allow hobbyists complete freedom of choice to use all their preferred or existing hardware in building the reef tank of their dreams.

G2+ Features

  • Includes a 3-in-1 ReefATO+ auto top-off system with temperature monitor and external leak detector

  • Assembly-ready piping now with extra bulkhead connectors in both Metric and USA sizes for customized setups

    • Adjustable height skimmer chamber
    • Bubble trap
    • Plug & play ready for ReefMat 500 or 1200 Auto Filter Roller (sold separately)

New to the G2+ -- 3-in-1 ReefATO+

Every REEFER G2+ model includes a ReefATO+, an exceptionally reliable and smart auto top-off system. The ReefATO+ is more than just an ATO-- it also includes an accurate temperature monitor and external leak detector, coupled with a smart controller that connects to the ReefBeat ecosystem. 

  • Fully-featured online digital temperature monitor accurate to 0.1 degree
  • Reliable leak detector with audible alarm
  • Slimline multi-input titanium probe water level sensor
  • Strong magnetic corner mounting bracket
  • Precise water level monitoring
  • Built-in safety shutoffs under the following scenarios:
    • Sensor isn't connected
    • Pump runs dry
    • Leak is detected 
    • Pump runs longer than normal
  • Track water level and temperatures in the ReefBeat app
  • Powerful, quiet, and slim 1.8" diameter pump that fits in most ATO reservoirs
  • ReefBeat connected smart controller included

Extra-fortified Glass and Marine-Spec Cabinets

The G2+ series of REEFER aquariums are rimless and constructed from ultra-clear, beveled-edge glass with an increased glass thickness of up to 19mm. These strong glass tanks sit atop newly fortified cabinet stands made of plywood and with Marine-Spec, water-resistant lamination. Each cabinet stand follows the contours of the aquarium glass, with the larger REEFER G2+ models featuring an additional “floating tank” aluminum support. Adjustable leveling feet & stainless steel hinges ensure a lasting and durable stand for your dream aquarium.

Improved Water Management & Plumbing

Up top, the G2+ REEFER systems employ a large overflow box with dual side-facing return pumps for optimal water circulation and increased surface skimming. The overflow box includes a lid which hides plumbing components, as well as easily-removable weir combs for quick cleaning and improved surface skimming. Water then exits from the overflow box and travels down an enlarged and rectangular inlet to the downflow pipe, allowing for reduced turbulence & quieter operation. All G2+ models also include a high precision valve on the downflow pipe, allowing for simple regulation to further tune your flow.

Reef-Ready Sump– Now ReefMat Compatible

As with the previous generation of REEFER, the G2+ sump includes a mechanical filtration compartment complete with micron filter sock(s) and filter cup(s) to keep large pieces of debris and detritus from clogging pumps and other pieces of equipment. This chamber can be alternatively used to house a ReefMat 500 or 1200-- no modifications required! Water flows from the filtration chamber into the adjustable-height skimmer compartment, where the water will be kept at a steady level to aid in the best performance for your choice of skimmer, or any other filtration components that you choose to include. The water will then flow through the final bubble trap and into a chamber where the return pump (not included) can be placed to pump water back through the Reefer tank's return plumbing.

3+2 Extended Warranty Plans

All REEFER aquariums include a standard 2-year warranty. Register your brand-new Red Sea system within 90 days of the original date of purchase and turn your standard 2-year warranty into 3 years at no extra cost. 1-2 year extended protection plans are also available for purchase through Red Sea's warranty registration page. That's up to 5 years of worry-free protection!

NOTE: The Deluxe models include 4x ReefLED 115 & Mounting arms & ATO System

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.
