Caribsea Arag-Alive! - Hawaiian Black 20lb

CaribSea Arag-Alive Hawaiian Black is a live aragonite sand for marine and reef aquariums, seeded with beneficial bacteria to shorten cycling, here in the larger 20 lb bag for bigger builds.

Key features

• Live aragonite already carrying beneficial bacteria
• Natural calcium source that helps buffer marine water
• Striking black substrate for a high-contrast display
• 20 lb bag covers a larger footprint

The right choice for a reef or marine setup; freshwater planted tanks want an aquarium soil instead. More gravel and substrate and marine salt and saltwater. Available for local pickup at our Lethbridge store.
