Macroalgae, Plants, and Sponges

Natural filtration, biodiversity, and living reef structure.

The Macroalgae, Plants, & Sponges Collection features functional and decorative macroalgae, reef-safe marine plants, and select sponges used in both refugiums and display aquariums.

Macroalgae are widely used for nutrient export, nitrate and phosphate reduction, and biological filtration, while also providing habitat for beneficial microfauna. Many species also enhance aquascaping by adding movement, texture, and natural reef aesthetics.

This collection supports reef keepers interested in ecosystem-based reef keeping, refugium systems, and sustainable nutrient management.
