ARM™

ARM™ Fine
With the highest solubility of any reactor media available (metastable at 8.2) it's typical CO2 consumption is much lower.

Contains:
381000 ppm Calcium, 590000 ppm Carbonate, 7390 ppm Strontium, 1050 ppm Magnesium, 56 ppm Potassium.
About 69 pounds per cubic foot
1 gal (00525), 50 lb (00555)

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
1 gal (00529), 50 lb (00559)

ARM™ Extra Coarse
A high magnesium reactor media. ARM™ Extra Coarse is still a complete reactor media containing not only calcium and carbonate, but essential trace elements as well.

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