GRO 20W Refugium LED
The Neptune Systems 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. This unit includes a Pipe Mount bracket which cleverly clamps to a section of your hard plumbing that has a 1-1.5 inch outer diameter (standard 3/4″ to 1″ PVC pipe). The GRO uses all its power to emit light in two specific wavelengths that are optimized for macroalgae growth – 455-460nm and 620-670nm. This combined with its rectangular shape (have you ever seen a round refugium?) means that the right light goes right where you need it – and minimizes nuisance algae growth in other areas of your sump due to light spillage.

Some of the most successful reef aquariums employ the use of a macroalgae-filled growth area or refugium for the purpose of nutrient control. Growing and harvesting macroalgae in a compartment in your sump, or in a full-blown refugium, is the natural way to reduce unwanted nutrients in your reef aquarium. It also creates a home and reproductive area for beneficial micro-fauna that consume waste and provide a food source for corals and fish. Growing macroalgae opposite your normal light cycle (called reverse daylight photosynthesis or RDP) also helps raise and stabilize your aquarium pH.
