Carribsea Ocean Direct substrate is different than all other live sand products on the market. Ocean Direct utilizes “Sea Breathe” technology, which preserves real live sand with its own original bacteria.
Every breathable bag of Ocean Direct is alive with up to 1000 times more beneficial bacteria than other preservation methods. Every grain of Ocean Direct is coated with bacteria and encapsulated by capillary action in a thin film of real ocean water. The thin film is open to the atmosphere for unparalleled gas exchange. This results in high counts of natural and beneficial bacteria with no noxious buildup of metabolic by?products. Contains a packet of Bio-Magnet clarifier to reposition any free floating bacteria to where they are most active: sand beds, live rock surfaces, and biological filtration media.
