Chaetomorpha Macroalgae

A refugium in the sump of a reef aquarium is a dedicated section designed to enhance water quality and support beneficial organisms. It often houses Chaetomorpha macroalgae, a fast-growing and hardy species ideal for nutrient export. As the Chaetomorpha absorbs nitrates and phosphates, it helps reduce algae growth in the main display tank, improving overall water clarity and stability. Additionally, the refugium can provide a safe habitat for copepods and other microfauna, which serve as a natural food source for reef inhabitants. A refugium with Chaetomorpha is an efficient and natural way to maintain a balanced reef ecosystem.
