Two Little Fishies ReBorn is a premium coarse aragonite media designed for use in calcium reactors. Composed of fossilized skeletons from reef-building corals, this media is sustainably harvested from the Western Pacific. As it dissolves within your reactor, it effectively replenishes essential elements such as calcium, carbonate alkalinity, strontium, and various trace elements, helping you maintain stable and ideal water parameters for a thriving reef aquarium.

The key feature of ReBorn is its coarse particle size, which promotes unrestricted water flow and allows for the easy diffusion of carbon dioxide. This design maximizes the efficiency of your calcium reactor and simplifies maintenance by preventing clogging. Unlike other media that can break down into mush, ReBorn dissolves completely, ensuring a clean and consistent performance over time. This package contains 8.8 lbs (4kg) of high-purity media, ready to support your reef's demands.

This product is ideal for intermediate to advanced reef aquarists who utilize a calcium reactor to automate the supplementation of calcium and alkalinity. It is particularly beneficial for those with high-demand systems, such as aquariums heavily stocked with SPS and LPS corals. If you are seeking a reliable, clean-dissolving, and highly efficient reactor media that minimizes maintenance and delivers consistent results, ReBorn is an excellent choice for your system.
