Arag-Alive Caribbean Reef from top substrate company CaribSea blends fine live sand and coral substrates for an authentic reef substrate perfect for reef aquariums, any marine aquarium or cichlid tank, plenums, sumps and nitrate reduction beds. This substrate is wet-packed to preserve its natural, beneficial marine bacteria, which helps cycle a new aquarium and continues to aid in the control of ammonia and nitrites after setup. It also features a special biofilm that allows new beneficial bacteria to rapidly colonize, and boosts denitrification with a bacteria-promoting Bacter-Vital Co-enzymic/bacterial solution.
