Nutrient-rich liquid food for corals and filter feeders.
Waterbox Phytoplankton is a premium algae-based liquid food that provides essential nutrition for a wide range of reef organisms. This carefully balanced formula blends phytoplankton, zooplankton, and vital nutrients to support coral coloration, growth, and overall system health.
Phytoplankton serves as a natural food source for soft corals, sponges, clams, and filter-feeding invertebrates, while also nourishing beneficial microorganisms such as copepods and zooplankton. Regular feeding with Phytoplankton helps create a more vibrant, biologically diverse, and balanced reef environment.
Key Benefits:
• Enhances coral color, growth, and vitality
• Feeds soft corals, sponges, clams, and filter feeders
• Supports populations of zooplankton and copepods
• Improves overall biological balance and biodiversity
• Provides essential nutrients for a thriving reef ecosystem
Recommended Use:
Ideal for soft corals and filter-feeding invertebrates.
Directions for Use:
Add 10 drops per 100 L (25 gal) every two days.
Do not dilute or mix with other coral foods in one container.
Avoid overfeeding, as every aquarium has different nutrient demands.
Refrigerate after opening.
