ARM Reactor Media Coarse 1 gal

Calcium reactors have evolved into several types
that require different media sizes. Because of this we now offer ARM^TM  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.

Works with many Tunze, Precision Marine, Korallin,
Schuran, Coralife, Knop, Coral Vue, Vorex , Octopus, and Pacific Coast
reactors.
