Sea Lettuce is a bright green macroalgae that makes an excellent addition to marine refugiums and reef aquarium systems. Known for its rapid growth and hardy nature, sea lettuce helps absorb excess nutrients such as nitrates and phosphates, supporting cleaner, more balanced water conditions.
This macroalgae thrives under strong lighting and does especially well in refugiums where it can receive consistent water movement and illumination. Because it grows in loose, leafy sheets, it is easy to harvest and manage as it expands.
Clean Sea Lettuce is also highly valued as a natural food source. Many herbivorous fish, snails, crabs, urchins, and other marine grazers enjoy it as a nutritious snack. Instead of discarding harvested portions, aquarists can offer them directly to livestock as a fresh, wholesome treat.
Ideal for refugium setups, nutrient export, and supplemental feeding, Clean Sea Lettuce is a practical and beneficial choice for both new and experienced saltwater aquarium keepers.
Great for:
- Refugiums and sump systems
- Natural nitrate and phosphate reduction
- Herbivorous fish and invertebrate feeding
- Easy harvesting and nutrient export
- Reef and marine aquarium systems
