Enjoy the benefits of natural filtration for your AIO (All-In-One) Aquarium with the versatile MagnaFuge LED. Unlike traditional fuge lighting, the low voltage MagnaFuge utilizes dedicated rare earth neodymium magnets to mount vertically or horizontally behind your AIO, and remains discreetly out of view. Designed for maximum macro algae growth, the MagnaFuge distributes 6500K spectrum evenly with 120 degree optics, and delivers an amazing 120 lumens per watt. Creating a refugium aids in the export of unwanted nutrients such as phosphates and nitrates, while stabilizing pH and oxygen levels throughout the day. They also provide a natural food source for your aquarium inhabitants, to create a true thriving mini-ecosystem.
