Maintaining low nutrient levels is key to a healthy and algae-free marine aquarium
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 (PSU WILL BE AVALIABLE SEPERATELY SOON)
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 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 (
An available gooseneck mount comes in two models: This has a traditional clamp style mount to attach it to the edge of your sump.
1. A sequestered place in your sump or filtration area that has adequate water flow.
2. A “start” of macroalgae such as chaetomorpha – get it online, from a LFS, or from a reefkeeping buddy.
3. A proper light source, like the GRO.
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?) mean 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.

REDUCE YOUR NUTRIENTS, THE NATURAL WAY, WITH A REFUGIUM
It’s easy! 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.Only three things are necessary to get started:1. A sequestered place in your sump or filtration area that has adequate water flow.
2. A “start” of macroalgae such as chaetomorpha – get it online, from a LFS, or from a reefkeeping buddy.
3. A proper light source, like the GRO.
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?) mean 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.
EASY PLUG AND PLAY SET UP
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 – and possibly even fly in the face of some “experts” – 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 LED, selected for optimal macro algae growth, and spreads them evenly across a wide, rectangular area. This enables the GRO to be placed very close to the macroalgae and increase its efficiency while minimizing wasteful light spillage.HIGHLIGHTED FEATURES:
