Neptune Systems - GRO LED Refugium Light With Flat Mount

Some of the most successful reef aquariums employ the use of a macroalgae-filled growth area or refugium for the purpose of nutrient control.
The GRO is a specialized, 20W LED light designed to grow many types of common macroalgaes (i.e. Chaetomorpha) using a specialized light spectrum which maximizes photosynthesis. It plugs directly into any available DC24 port in your Apex ecosystem, or alternatively, it can also be run completely standalone.

Compact, flat, rectangular LED grow light measures 8.7″ X 6.1″ X 1.4″ making it the perfect fit for the smaller refugium compartments in many modern aquariums — as well as those that wish to grow macroalgae in a separate refugium.

84 LEDs in four colours create an evenly distributed spectrum optimized for macroalgae growth. Two key wavelengths for algae photosynthesis are emphasized — 455-460nm and 620-670nm.

Large, rectangular form promotes better algae growth, while reducing nuisance algae from light spillage, as intensity is evenly spread across a refugium area that is almost always rectangular. The GRO can effectively cover a refugium area up to 18″x24″

Round, spotlight style refugium lights, often create uneven spread of intensity. This causes hotspots that lead to algae burning or stunted growth. With the GRO, the 84 LED in a rectangular form factor create even light intensity and no hotspots.

Nuisance algae on in our sumps and on our equipment is normally one of the downsides of using a refugium. Since most refugia are rectangular, the GRO projects light in a similar manner. Also, with its low-power, distributed LED design, the GRO can be placed very close to the water surface further limiting light spillage and therefore nuisance algae.

The GRO is IP64 rated which means splashes and salt spray will not take it down. This means it can safely be placed close to the water surface, maximizing light effectiveness, and reducing wasteful light spillage that often causes nuisance algae in other parts of a system.

Power the GRO using an available DC24 connection in your Apex ecosystem (on Energy Bar 832 or 1LINK module). If you do not have an available DC24 port, or you wish to use the GRO without an Apex, a power supply is available so it will operate standalone.

An available gooseneck mount. Comes with a Flat mount to attach it to your sump.
