Reef Code A - Brightwell Aquatics

Reef Code A is the calcium component of a balanced two-part dosing system designed to maintain calcium and alkalinity at natural seawater levels. When used in equal parts with Reef Code B, it delivers ionically balanced calcium and carbonates to support the health and growth of reef-building organisms such as corals, clams, and calcareous algae. Formulated by marine scientists, Reef Code A is highly concentrated—stronger than many competing products—and contains no phosphates, silicates, or organic additives. It simplifies calcium supplementation while ensuring precision and stability in reef aquariums. Key Benefits:   Delivers calcium in the same ratio found in natural seawater (when used with Reef Code B) Supports skeletal growth in SPS, LPS, clams, and coralline algae Highly concentrated formula for efficient dosing Phosphate-, silicate-, and organics-free Ideal for all reef aquarium systems   Guaranteed Analysis (per oz.):   Calcium: 60,000 ppm Magnesium: 1,500 ppm Strontium: 1,200 ppm   Ingredients: Purified water, calcium chloride, magnesium sulfate, strontium chloride, magnesium chloride Usage Tips: Shake well before use. Do not mix with Reef Code B in the same container. For best results, maintain magnesium between 1,290–1,320 ppm before use. Basic Dosage: Add 5 ml per 25 US gallons every other day or as needed to maintain calcium between 412–450 ppm. Advanced: Each ml raises calcium by ~16 ppm per 1 gallon. Use a reliable test kit and adjust dosage based on your system’s daily calcium consumption. Caution: May irritate eyes or skin. Rinse thoroughly if contact occurs. Keep out of reach of children. Not for human consumption.
