Two Little Fishies Reborn is a high-purity aragonite media specifically designed for use in calcium reactors. This premium media is derived from fossilized coral skeletons, providing a natural source to replenish calcium, alkalinity, strontium, and other essential trace elements consumed by growing corals and coralline algae. It effectively automates the maintenance of these critical parameters, creating a stable and thriving reef aquarium environment.

This 8.8lb container of Reborn features a coarse grain size that promotes excellent water flow and prevents compacting or channeling within the reactor chamber. Its composition is rich in calcium carbonate, which dissolves slowly and evenly when exposed to the low pH environment created by CO2 injection. This controlled dissolution ensures a consistent and balanced effluent is delivered back into the aquarium, supporting robust coral skeletal growth without dramatic swings in water chemistry.

Reborn Calcium Reactor Media is ideal for reef hobbyists with high-demand systems, such as aquariums heavily stocked with SPS corals, clams, or fast-growing LPS. By providing a steady supply of essential building blocks, it eliminates the need for daily manual dosing of two-part solutions, making it a perfect choice for aquarists seeking greater stability and automation for their advanced reef tanks.
