Manufacturer information

EcoTech Marine has revolutionized the way people think about water movement in reef aquariums. Our technologically superior pumps produce unmatched broad yet gentle flow, while placing the motor outside the tank—preserving the beauty of your aquarium and enhancing the health of your aquarium ecosystem. The EcoTech leadership team consists of aquarium enthusiasts and engineers with a penchant for challenging the status quo. When EcoTech took root in the science labs of Lehigh University and University of Oklahoma, we realized there were serious differences between the native aquatic ecosystems in nature and the terrestrial habitats created in aquariums—and that little was being done to address this gap in the marketplace. Since that day, we have worked tirelessly to improve the “state of the art” to enable our customers to have the healthiest, safest and smartest aquarium possible. That’s why our products offer a wide variety of easy-to-program modes and have been thoroughly tested and endorsed by marine-biologists—making it the most versatile and life-like pump on the market.

No, I would not recommend this.

Arms sag

I have four arms on my 180 gallon tank and all of them sag -- and at different amounts. When people look at my tank they regularly comment that the lights look like they are going to fall into the tank.

I have other lights that are much cheaper and don't have this issue. It is so noticeable I regret purchasing radions.

Pros: works

Cons: not height adjustable (but that is why it is strong too)

RMS Arms

I initially bought two Ecotech r30 LED lights and used the single arms for the light supports. I then decided I wanted to use three lights and had to switch to the RMS ARMS and rail system. This has worked well. The light support system is well built, solid, works perfectly, and is stable despite having only two legs versus the standard four for most lighting systems. It's an expensive set up, but it is working well for me.
