ARM™ COARSE

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.

Contains:
416000 ppm Calcium, 577000 ppm Carbonate, 3300 ppm Strontium, 1400 ppm Magnesium, 56 ppm Potassium.
About 70 pounds per cubic foot
