Super clear glass, stylish cabinet, auto top off water system built in and a professional designed filter sump. It really doesn’t get better than this. These tanks make the perfect addition to any home or condo. They are also silent ! The plumbing has been designed to avoid gurgling or water sounds so you can enjoy your aquarium in silence. If you have the room go with the red sea reefer 250 G2+ over the smaller models, you wont regret it and will give you years of enjoyment and relaxation before you even considering going bigger 🙂

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 newly improved 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. New to the G2, 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.
Additional features of the Reef-Ready sump system include an optional refugium compartment for growing chaeto or other macroalgae, as well as an RO reservoir that can hold a few days worth of top off water to keep the water level, salinity and flow rates consistent throughout the tank.
3+2 Extended Warranty Plans
All REEFER aquariums have included a standard 2-year warranty. With the new G2 models, you can now purchase an additional 1-2 year warranty plan when registering your new system online. That’s a total of 5 years of worry-free protection!

Equipment Recommendations
Here are our Fragbox personal recommendation to complete your red sea reefer 250 installation.
Lighting
AI Hydra 32HD or Ecotech XR15 Blue
Lighting is probably one of the most important consideration you will make when building a salt water aquarium. It also happen to be the most expensive. This is the one place you don’t want to cheap out. Both Aqua Illumination and the Ecotech Radion make amazing choice for this tank. These brans are acutally owned by the same American company and simply have no competitors when it comes to powerful led lightening for reef tanks. Intense dimmable power for soft coral or even the most light demanding. Superb customer service and huge online community of users. Simply the best and pair beautifully with ant redsea reefer.
The red sea reefer 250 in our showroom is currently running 2 of the xr15 blues. You can see our video review on the xr15 on youtube channel here.
Skimmer
Protein skimmer are very important in nutrient export in a saltwater aquarium. The bubble magus brand of skimmers pairs perfectly with the red sea reefer 250 and they offer high quality, easy to use and clean, silent and reliable skimmers. Not to mention easy on the wallet ! This brand is always our preferred brand of skimmer and these size pair beautifully with the reefer 250. It fits snugly in the sump but still gives you lots of room.
Check out our youtube video review of the bubble magus skimmers here.
Return Pump
Amazing, Italian made , silent and 5 year warranty. I know, its crazy who does a 5 year warranty on anything these days? Let a lone a pump running in salt water. We always recommend the sicce brand of pumps. The pump is like the heart of your aquarium. It send water from the sump (filter) up to your display tank. If it stops the blood (water) stops flowing. Don’t you want the most reliable heart ? Go with sicce, its what we use.
Check out this youtube video on deciding on what equipment to run the reefer 250 white in our store.
Easy to program, reliable, 3 year warranty. Basic, simple and does what its supposed to do. This Italian made heater is our preferred brand of heater. The 200w cobalt heater is enough for this aquarium unless you plan on putting it in a basement, you may want to consider going up to the 250w model.
Wavemakers
Flow is crucial is a salt water aquarium, you want to recreate natural ocean currents. The reefer has quiet a bit of water to move around so you will want something with decent power. When it comes to wavemakers there are SO MANY options of the market. For budget friendly and reliable water movement go with the Jebao sw-8. For this aquarium you would need 2 or 3 of them. Its going to depend on how you set your rock work. For the best go with the MP10 from Ecotech or the nero 5 form AI. If you choose the AI light like the prime or hydra, they all run of the most amazing app and will connect seamlessly to your smart device. Check out video review on the nero 5 for info. There is just to much to type. For either option you will need two pumps. We have less expensive options we would happy to show you in store as well.
Other than the above listed equipment, in order to start this tank you will need sand, rock, salt, something to measure salt and start bacteria. We are here 7 days a week to help you design your perfect dream salt water system. Please feel free to call, email or visit us in person for info.
Specification
The incredibly popular REEFER series aquariums from Red Sea have been redesigned into a brand new series of tanks – The REEFER G2. Red Sea hasn’t moved too far away from their original vision of the REEFER tanks and the overall appearance has gone unchanged. The improvements to the G2 series tanks are focused on the quality of craftsmanship, filtration performance, and an optional extended warranty.


Upgraded Reef-Spec Ready Sump
The new glass sump features a Reef-Mat ready mechanical filtration compartment with removable micron filter socks and media cups making it easy to install the Red Sea Reef-Mat Fleece Roller. As with the original REEFER sumps, you still get a dedicated skimmer chamber with an adjustable water level, an optional refugium chamber, and an integrated ATO system with a freshwater reservoir.


Improved Water Management System
The easy assemble plumbing has always been a benefit to Red Sea aquariums and the new plumbing kits feature an improved precision flow control for the primary drainpipe and dual return nozzles to help distribute flow throughout the display. Red Sea also created a custom pipe connection kit making it easy to connect US standard PVC pipes to the stock Red Sea plumbing which is a great bonus for advanced reef tank owners.


Fortified Plywood Stand
The laminated plywood cabinets follow the contour of the display aquarium creating that sleek aesthetic. Plywood makes it easy to mount your favorite Reef-Spec equipment and controllers while maintaining structural stability. The stand doors come with an epoxy coating for extra protection against harsh saltwater as well as stainless steel hinges and adjustable leveling feet. Larger tank models are also extra-fortified with aluminum supports that allow for plenty of access down below the tank without bulky braces getting in the way.
Optional 5-year Extended Warranty
All REEFER G2 aquariums are rimless and made from thick ultra-clear glass with beveled edges and clean silicone lines. Right out of the box your REEFER G2 comes with a 3-year standard warranty with the option of an additional 2 years of warranty support available directly from Red Sea.
