Caulerpa lentillifera, also known as sea grapes, is a fast-growing macroalgae that is particularly well-suited for use in a refugium. This attractive green algae forms long strands with small, grape-like balls that are not only functional but also an aesthetic addition to your sump or refugium.

Benefits in the refugium:

• Nitrate and Phosphate Reduction – Helps reduce excess nutrients in aquarium water, thus preventing algae growth in the display tank.
• Fast Growth – Absorbs nutrients quickly due to efficient growth, provided adequate light and flow are present.
• Microfauna Shelter – Provides a safe habitat for small organisms such as copepods and amphipods, which benefits the biological balance and serves as a natural food source for fish and corals.

Important care:

• Provide adequate lighting and stable water values.
• Avoid extreme temperature fluctuations or drastic changes in salinity.
• Can easily be pruned back if overgrowth occurs.

Caulerpa lentillifera is an excellent choice for both novice and experienced hobbyists who want to use their refugium as a natural filter and enrich their ecosystem at the same time.
