Neptune GRO Refugium Light with Flat Bracket 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 colors 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 spre
