What lights for a refugium?

A refugium is a supplementary aquarium that is kept alongside a saltwater or reef tank. Its primary function is to facilitate the continuous circulation of water in and out of the primary tank for enhanced filtration. The key objective of a refugium is to eliminate nitrate using green plants, particularly macroalgae, which utilize nitrate as a nutrient for growth and propagation. As a result, you can effortlessly remove a portion of the population for maintenance purposes.

The primary goal of a refugium is to cultivate macroalgae at the highest possible level. The aesthetics of the refugium are not a priority. Therefore, the selection of the best LED light for plant growth is critical for a refugium. GAKO refugium LED lights with higher amounts of red and blue in the spectrum have been proven to foster the growth of green macroalgae more effectively than white lights.
