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.
Features
- Compact and efficient light output
- 84 LEDs, optimum growth spectrum
- Large surface with even distribution
- IP64 Water resistant design
- Can operate standalone with option power supply
- Includes gooseneck and pipe clamp 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. 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.
Easy Plug & Play Setup
Remove the GRO from the box, plug it into one of your available DC24 connections on an Energy Bar 832 or 1LINK module, select GRO from the tasks menu, and in just a couple of minutes a step by step wizard will have it set up and scheduled.
Better Macroalgae Growth Using Less Power
It may seem counterintuitive, but with far less power than its competitors, the GRO promotes thick, healthy, and abundant macroalgae growth. The GRO does this by using 84 low-powered LEDs, selected for optimal macro algae growth, and spreads them evenly across a wide, rectangular area. This avoids hot spots in the lighting output and enables the GRO to be placed very close to the macroalgae, increasing its efficiency while minimizing wasteful light spillage.
NO Apex or DC24 Port Necessary - Works with the 24v DC Power Supply
Maybe you don’t have a free DC24 port, or even have an Apex at all yet – no worries – with the optionally available 24v Power Supply, the GRO can be used on any aquarium as a standalone refugium light.
