It is formed as a spherical bead for optimum hydrodynamics, and will not pack. It permits maximum water flow and contact with its high density. Use 250 mL of Matrix for each 200 L (50 US gallons) of water. This high efficiency spherical carbon has very little impact on pH due to low ash content and the lowest leachable phosphate level on market.
