Neptune Systems GRO MacroAlgae Light

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 Neptune Systems GRO MacroAlgae Light 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 LED grow light with 84 LEDs in four colors, two key spectrum ranges for optimal macroalgae growth
• Large, flat area of illumination promotes better growth as it creates a much more even spread than single, spotlight-style lights.
• Distributed LED design means no light hotspots that can burn the macroalgae
• Less light spillage — IP64 water resistance means it can be placed very close to water "” reducing the growth of nuisance algae elsewhere
• Covers a refugium area up to 18"x24"
• Plugs directly into DC24 connection on an EnergyBar832 or a 1Link module.
• Dimensions: 8.7"³ x 6.1"³ x 1.4"³ (light panel itself less than 1"³ high)
• Works with any Apex model, including the Apex Classic family.
• Operates standalone, without an Apex, with the purchase of an optionally available power supply.
• Mounts using the optionally available, flexible gooseneck, with one of two clamp styles
