D-D ROWAlith W Calcium Reactor Media | 9-15 mm co2 Gauge ensuring you have air trappedROWAlith W is a complete calcium reactor media which composed of natural aragonite with a high concentration of calcium, carbonate, magnesium, strontium, potassium and other essential trace elements. This is the perfect media necessary for the growth of stony corals, such as SPS and LPS. Large media of 9 15mm grain size ideal for calcium reactors. The large grain size it will resist tracking of water through the media, often experienced when running
