What Is a Refugium?

A refugium is a dedicated area within your aquarium that serves as a sanctuary for small, beneficial organisms, including microalgae, copepods, and amphipods. These organisms play a vital role in the ecosystem by helping to control nutrient levels, remove detritus, and serve as a food source for your aquarium’s inhabitants.

The Importance of Proper Lighting

Proper lighting is essential for the health and growth of the organisms in your refugium. It’s not just about brightness; it’s about providing the right spectrum of light to support photosynthesis and encourage the growth of microalgae.

Types of Refugium Lights

LED Lights

LED lights are a popular choice for refugiums due to their energy efficiency and customizable spectrum options. They provide ample light while keeping energy consumption low.

T5 Lights

T5 lights are known for their high-intensity output and even light distribution. They are ideal for larger refugiums and can support a variety of macroalgae species.

Metal Halide Lights

Metal halide lights are powerful and can penetrate deeper into the water, making them suitable for larger or deeper refugiums. However, they can generate more heat and consume more energy.

Factors to Consider When Choosing the Best Refugium Light

Light Spectrum

The spectrum of light your refugium light emits should mimic natural sunlight to support photosynthesis. Look for lights that offer a balanced spectrum of blue and red wavelengths.

Intensity and Coverage

Consider the size of your refugium when selecting a light. You’ll want to ensure that the entire area receives adequate light coverage.


Refugium lights need to withstand a humid environment. Look for lights that are built to last, with corrosion-resistant materials.
