Red Sea Reefer G2+ 250

Red Sea Reefer G2+ 250 Aquarium is designed for hobbyists to create and manage their ideal reef tank with advanced filtration, water management systems, and customizable hardware options.

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.

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.

Bought a "Used like new" watch. Doesn't keep time
Color: Black/Black/Black/Fast-Wrap
I've had this for a few weeks. Since then, it's lost about 30 seconds. I'm not sure if it's this specific unit that has the issue or the mechanism itself. It's a shame because it's a killer looking watch.

Light, retro watch
Color: Brown/Brown/Natural
This is a light, comfortable and retro-stylish watch. A mixture of plastic, canvas, and faux-leather makes a good match for a college professor's tweed jacket with leather shoulders and elbow patches. It looks and feels cheap but it's actually a pretty good watch. Mine has a high contrast face making it easy to read. The hands have lume on them but it only glows for a few minutes. There is an indiglo feature when you press the winder so that's great. The day window is tiny and almost unreadable even with reading classes but other than that it is very functional. You can adjust the time and day independently (so you don't have to wind through 100+ hours to get the right day displayed). The winder setting to select between time and day adjust is very finicky. Fortunately you only need to adjust the day 5 times a year. The weakest part is the build quality. I'm not expecting Rolex, but the case corrodes really badly and the strap is short and the stitching failed so it fell off my wrist in about 6 months. I replaced the strap with a better one but the case corroded so badly I tossed it within a year. Other than looking cheap, poor build quality, and being thicker than I would like, I think this is a good watch.

A nice, comfortable watch.
Color: Black/ Green
A nice inexpensive everyday watch. It is accurate, a nice size for my wrists. You barely feel it as it is so light. it has a nice clear face Andy only gripe is that I wished it had slightly better loom. Other than that it is a great watch for the money and this is coming from someone with 30+ watches in my collection in all price ranges. It has earned its way into my regular watch rotation.

Good Watch for use in water.
Color: Black/ Green
Here's the deal. It's an excellent plastic watch. If you don't abuse it, it should last years. The advantage of metal bodies and crystal faces, is that they're lot more resistant to scratches compared to plastic, BUT they weigh a lot more than plastic watches. I love the size of this watch while at the same time, it surprisingly light on the wrist. Therefore it doesn't move all around like a heavy steel watch. I hardly know Im wearing this plastic watch. Also, I went snorkling offshore for a week with this watch, no leaks, no problems. It will stand up to water fine. So, if you don't abuse it, its a pleasure to wear, lightweight, waterproof, doesnt slip around, looks good. I imagine the battery should last 3-5 yrs like my last plastic quartz watch. For the price, its a very good watch.
