Caribsea Seafloor Special Grade Reef Sand, 15 lb

CaribSea Seafloor Special Grade is a fine dry aragonite reef sand, a clean, uniform substrate for marine and reef aquariums that also helps buffer water chemistry.

Key features

• Fine aragonite grain suits reef and marine displays
• Natural calcium source that supports stable marine pH
• Dry sand, so rinse and add to a new or established tank
• 15 lb bag

Being dry sand it does not carry live bacteria, so a new tank still needs to cycle; pick Arag-Alive if you want a seeded head start. More gravel and substrate and marine salt and saltwater. Available for local pickup at our Lethbridge store.
