This substrate is different than all other reside sand products available on the market. Ocean DirectTM utilizes “Sea Breathe” technology, which preserves real reside sand with its own original bacteria. Each breathable bag of Ocean DirectTM is alive with as much as 1000 times more really useful bacteria than other preservation methods. Each grain of Ocean DirectTM is coated with bacteria and encapsulated by capillary action in a thin film of real ocean water. The skinny film is open to the ambience for unparalleled gas exchange. This leads to high counts of natural and really useful bacteria without a noxious buildup of metabolic by‑products. Ocean DirectTM gives you a thriving, natural aquarium in minutes!
