One Red Sea Grand Prize Valued at $2000+

Reefer 250 ($1644 value)


Red Sea’s REEFER series of reef systems provide advanced hobbyists with a solid foundation for building a fully featured reef or marine aquarium.

The REEFER series combines a contemporary, rimless, ultra-clear glass aquarium with a stylish cabinet and a comprehensive water management system including a professional refugium ready sump with integrated automatic top-up and Red Sea’s unique silent down-flow system.

The REEFER series is designed for ease of operation while enabling the advanced hobbyist to install an unlimited choice of lighting, filtration, circulation, and controllers to create a uniquely customized system.

Features include:
  • Rimless, ultra-clear, beveled edge glass aquarium
  • Elegant, marine-spec, laminated, plywood cabinet with adjustable feet
  • Assembly-ready piping – no gluing required
  • Professional refugium ready sump with adjustable height skimmer chamber *
  • Silent, regulated down-flow system with emergency overflow
  • Integrated automatic top-up system with reservoir
  • RO liter reservoir that can be slid aside when necessary for pump maintenance. (not for 3XL900)
  • 90cm (36″) long/250 liter (65 gal) capacity
2x EcoTech Radion XR30 G5 Pro ($890 value each)


Radions are the standard in aquarium lighting for a reason. Each generation has built upon the successful results of the last, incorporating the latest in design and technology to bring us a state-of-the-art light that blends proven results with greater ease of use. Ecotech Marine has spent significant time and effort in developing and testing lighting programs, such as the popular SPS AB+, that deliver maximum results from their fixtures and bring out the best in our corals.
  • Flexible Spectral Output
  • PAR at the Ranges Needed
  • More Even Spread
  • Overall 35% More Light
  • Beautiful Caustics
  • Smooth Color Mixing
  • 10 Channels
  • Proven Halide Spectrum and Previous Pro Spectrum
  • Wireless Mobius App control—No extra equipment

Next Level Color

Color from the G5 is impressive. Blue or Pro, your coral will pop. With the G5 Pro, you get a more even distribution of spectrum for a balanced and natural lighting setup that can emulate metal halide output. G5 brings speed of growth, intensity of fluorescence, and nuance of color rendition to new heights. Crafted with the best LEDs, the optimized output from next-generation HEI Optics, and more color channels, Gen 5 is in a class of its own.

Beyond Peak PAR

More powerful than ever before, the Radion lineup delivers more coverage per fixture. The Radion’s optical system provides smooth color mixing, wide but even spread, and balanced intensity that fills the aquarium. The new single cluster design and optimized HEI Optics cut hot-spot PAR by 30% while providing 35% more total output. In the aquarium, this translates to more usable light over more area, creating the widest possible ideal par from your coral.

Advanced Heat Management

EcoTech Marine aims to produce the most minimally intrusive reef aquarium equipment available. The G5 continues to showcase Radion’s sleek styling and small footprint, but is now even quieter. A completely redesigned fan and newly evolved heatsink cool the Gen 5 more efficiently, allowing the fan to run at lower speeds. Your ears will notice a difference.


The Generation 5 sets the mood with two dedicated low output moonlight LEDs, each on an independently controllable channel.

Mobius Control

More colors mean more channels, and with Mobius, programming and controlling your G5’s increased power is even easier and faster. Mobius means almost instant setup and programming. Local wireless control and programming can be accomplished with either current OS version iOS or Android smart device. Off-site WiFI control is missing from the G5 at launch but will be enabled in the near future. Once again, the Radion will set new standards for technologically advanced and innovative control.

Multiple Flow Modes​

Lagoon Mode

Lagoon Mode

Simulating a low-energy lagoon. The QuietDrive motor slowly changes, recreating the gentle currents of a lagoon environment.

Reef Crest Mode

Reef Crest Mode

Simulating currents found around high energy reefs. The pump changes speed frequently emulating crashing waves and tidal surges.This is a great mode for SPS corals.

Gyre mode

Gyre Mode

Uniform circular flow creates motions that help transports water from one side of the tank to the other. With two pumps paired in Gyre Mode, you can oscillate between a clockwise and counterclockwise gyre that lasts from 2 seconds to 2 hours.

Short Pulse Mode

Short Pulse Mode

Strong short pulses that can be set at intervals of 0.2 seconds up to 2 seconds. This mode can create a standing wave in your tank with the correct frequency.

Tidal Swell Mode

Tidal Swell Mode

A harmonic balance of the ever changing conditions found in the ocean. TSM will vary from calm flow all the way up to chaotic high flow and it even has a pre-programmed detritus cleaning surge that will help suspend particles to be swept into the filtration system.

Nutrient Transport

Nutrient Transport Mode

NTM is programmed to create a two-phase circulation flow mode. Phase one consists of wave motions to help stir up and suspend detritus while the second phase incorporates surging motions to help push particles towards the overflow and down into the filter system. This is our favorite mode and is especially great for sensitive corals like LPS and SPS.

Function Modes​

Feed Mode

Feed Mode

Pause all of your wireless Ecotech Pumps at the push of a button. Pumps will turn down to an idle speed allowing you to feed your tank without the food being pushing into rocks or into the filtration system.

Night Mode

Night Mode

Simulate a calmer environment for night time hours. Night Mode can be enabled or disabled with custom hours programmed to automatically turn on and off.

Wave Auto Tune

Wave Auto Tune Mode

Create a standing wave in your aquarium to help sweep detritus and other foreign particles from the sandbed. It is amazing what will magically float out of the rocks when a standing wave is created. We highly suggest pairing two wireless pumps for this mode to get the full effect!

Mobius Programming

Access and program your Vortech pumps through your mobile device to access a myriad of features. A defining characteristic of EcoTech equipment is the versatility and power of control offered to the aquarium hobbyist. The Mobius app is packaging all this capability in a way that makes programming and control intuitive, quick, and painless.
