Carib Sea ARM Reactor Media Course 1 Gal 3.78L

Calcium reactors have evolved into several types that require different media sizes. Because of this we now offer ARMTM Coarse for rapid upflow type reactors that have become so popular. This coarse grade of ARMTM will prevent the clogging and upkeep associated with fine media and these reactors. Works with many Tunze, Precision Marine, Korallin, Schuran, Coralife, Knop, Coral Vue, Vorex , Octopus, and Pacific Coast reactors.
