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.

Love this sink organizer
This fits really well alongside our sink. Keeps the soap containers off the counter so the water drains off and keeps things much neater. When the tray is full, simply pour the water out, rinse, and put back.

Missing Dividers
Color: Black, Size: 9.4*4.1*5IN
Disappointed it was missing the adjustable dividers. Not great to hold dishwashing brushes. They slip right threw the side.

Sturdy. Built to last. It solves all the problems my old organizer had. Very satisfied.
Review for ARTLEO Kitchen Sink Caddy with Super Water Absorbent Diatomite Stone Sink Tray, Fast Drying Sink Organizer with High Dish Brush Holder Sponge Holder for Kitchen Sink, Stainless Steel This appears to be a sturdy organizer of stainless steel painted with a good amount of black protective paint. I ordered it to replace an inferior organizer of the same material (made by a different company altogether). This one solves the problems I had with my previous organizer which had begun to rust and break apart after six months of use. The narrow steel bars on the bottom shelf of this new organizer are supported by wider steel flats in the frame that will prevent them from breaking off the frame. (My old organizer bars broke because they were barely welded onto the frame and the repeated "pushing down" of my soap pump-bottle eventually broke them apart from the frame). The pads that prevent it from sliding across my counter in big waves (we live and travel on a boat) are secured around the steel legs as opposed to just being glued onto the bottom (like the pads of my previous organizer were, which fell off). There is no metal hanging over onto the sink edge to cause rust (like the metal that had caused rust with my old organizer.) The dish-brush holder can fit on the inside of the frame or it can hang on the outside of the organizer, which is nice because it makes more room if you have many tools that you like to use at the sink. And it can be compact if you don't. Be cautious not to remove the hanging part (dish-brush holder) too often because repeated wear can cause the paint to rub off and it could begin to rust. The "Water Absorbent Diatomite Stone" is new to me but it seems to be working just fine. I assume I will have to clean out the ridges of it as gunk forms there, but that would be the case with any sink organizer tray. I am very satisfied with this organizer, it is robust and it solves all the problems I had with my previous one. The price is on the higher side of similar organizers, currently priced at $23.99. All the best, Mrs. dr
