A High-Magnesium Calcite Aragonite Blend
Calcium reactors have evolved into several types that require different media sizes. Because of this we now offer ARM™ Coarse for rapid upflow type reactors that have become so popular. This coarse grade of ARM™ will prevent the clogging and upkeep associated with fine media and these reactors. Approximately 70 pounds per cubic foot (70#/ft3).
- 275,200 ppm calcium
