Two Little Fishies ReBorn Calcium Reactor Media (8.8 lbs) is a premium, coarse-grade biological calcium carbonate medium composed of sustainably sourced fossilized skeleton remains of wild stony corals (Acropora sp.). Engineered specifically for automated calcium reactors, it dissolves predictably under acidic conditions to provide demanding marine reef displays with a balanced supply of calcium, carbonate alkalinity, strontium, and vital trace metals.
Core Physical and Material Properties
Total Package Weight: 8.8 lbs (4 kg) packaged in a durable dry box.
Skeletal Structure Format: Coarse, weathered coral bone fragments roughly 1 to 2 inches (2.5 to 5 cm) in length.
Porous Matrix Advantage: Because the material consists of genuine aragonite skeleton structures rather than crushed marble or dense limestone, it preserves the natural hollow canals of wild coral polyps. This maximizes the overall chemical surface area exposed to acidic water.
Sustainable Origin: Mechanically harvested from an ancient fossilized, inland coral reef formation, ensuring zero destruction or impact to living ocean coral reef ecosystems.
Performance and Equipment Benefits
Anti-Channeling Architecture: The irregular, coarse finger-like branches prevent the media from compacting over time. This preserves open pathways for high-volume water passage, completely eliminating the pump-stalling backpressure and localized flow dead-zones common with fine sands.
Mild Reactive Solubility: ReBorn features high chemical solubility, actively breaking down and releasing its concentrated minerals at a mild internal chamber pH threshold of 6.5 to 6.7. This efficiency minimizes the total volume of carbon dioxide (CO₂) gas your regulator must inject to maintain parameter stability.
Phosphate and Impurity Safety: The fossilized material is heavily processed and washed to remove all organic matter and ancient sediment. This ensures the dissolved effluent will not leach unwanted phosphates or silicates that could fuel sudden nuisance hair algae or diatom outbreaks.
