Purple Tech contains specific concentrations of calcium, magnesium, strontium, trace minerals and carbonates designed to stimulate the growth of purple coralline, green calcareous macro-algae and stony corals. When aquarium systems require more than just the basics — Coralife® steps in. From the all-inclusive BioCube® aquariums to cutting-edge lighting, equipment, Water Care, and more. Coralife is designed to simplify the complexities of this mesmerizing hobby.

• Coralife® Purple Tech is designed to provide nutrients required by coralline algae and stony corals.
• Contains kelp extract, a natural source of potassium, which helps improve the growth of purple coralline and green calcareous macro-algae such as Halimeda.
• Directions: Shake vigorously for 10 to 15 seconds immediately before each use. Add 5-10 mL (1-2 tsp) per 55 gallons of aquarium capacity directly to an area with high water flow each day until target calcium and alkalinity is reached. Note, due to its high concentrated formula, dosing will cause cloudiness that will dissipate within an hour.
• It's recommended that Coralife® Purple Tech be added to the system at night, in order to counter the natural tendency for pH to decrease during this time. It also allows for the aquarium to clear.
• Caution: Not for human consumption. Do not taste, swallow or breathe. Avoid contact with skin as it may cause irritation. If in eyes, immediately flush with water for 15 minutes. Do not mix with household chemical. KEEP OUT OF REACH OF CHILDREN!
