Overview

• High-purity, magnesium-rich mineral that may be employed in traditional calcium reactors,
  or even blended in to pre-existing aquarium substratum, to gradually increase and maintain
  the magnesium concentration in the system.
• Provides magnesium, which helps regulate the balance between calcium and carbonates in
  aquarium water, and is a component of aragonite, the mineral secreted by reef-building
  organisms to form skeletal material.
• Composed of magnesium, calcium, and carbonates.
• Optimal average particle size for use in media reactors and calcium reactors.
• Free of chloride and sulfate.
