Deltec's calcium reactor media is a holistic blend of natural aragonite, enriched with high concentrations of essential elements such as calcium, carbonate, magnesium, strontium, potassium, and other vital trace elements. It offers the ideal nourishment needed for the proliferation of stony corals, including SPS and LPS types.

The media, featuring a substantial grain size of 9-18mm, is optimal for calcium reactors. Thanks to its large grain size, it prevents the common issue of water tracking often seen with smaller grain sizes in larger, non-fluidized reactors. Sourced from ancient coral deposits, Rowalith W ensures the right Magnesium levels are maintained for your hard corals.
