Refugium Lights

Proper lighting is essential for a successful refugium, especially if you're growing macroalgae like Chaetomorpha to help manage nutrients. This collection of refugium lights includes compact, high-PAR options designed specifically for algae growth. Whether you're running a built-in rear chamber or a dedicated refugium section in your sump, quality refugium lighting promotes fast, healthy growth and better nutrient export.

From clip-on LEDs to full-spectrum grow lights, you'll find fixtures that are efficient, reliable, and designed with reef tanks in mind. A strong refugium light for saltwater aquariums not only supports macroalgae but also helps stabilize your system by lowering nitrates and phosphates. It's a simple, natural way to improve water quality and add long-term balance to your reef.
