Details

Hawaiian Black gravel is suited to marine tanks. It's ready to work, clears quickly, and contains millions of live bacteria to cycle super fast and create a natural biological balance. Arag-Alive substrates suppress the dreaded "new tank syndrome", compresses the ammonia cycle, and discourages nuisance algae. In fact, independent labs prove Arag-Alive cycles days faster than other brands of live sand.

Key Features:

Typical Size: 0.25 - 3.5mm
Average Density: 80 pounds per cubic foot
