NICE LOOKING LIGHT. Not much I dont like on this sleek design, good lighting. and its neptune so great stuff. The thing i like most is the slender body and great coverage for a refugium light.

Entry 1. I like the shape/output of the light. Matches the shape of refugiums, unlike some other brands

The Neptune Systems GO & GRO Contest!

Reef2Reef is proud to team up with Neptune Systems to bring you a fantastic giveaway where one winner will receive one of the newest additions to the famous line of Neptune Systems products, the GRO Macroalgae light! 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.
