  5. CaribSea Ocean Direct Live Sand 5 lbs.

    CaribSea Ocean Direct Live Sand 5 lbs.

    $6.95

    CaribSea Ocean Direct Live Sand 5 lbs. Simply Natural - Enjoy this real Caribbean live sand in a breathable bag with no added chemicals or special processing. Simply Effective - Ocean Direct is different thanall other live sand products on the market. This live sand utilizes patent pending Sea Breathe lazer technology which preserves real live sand with its own original bacteria. Every bag of Ocean Direct is alive and breathing 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. Each bag includes a packet of Bio Magnet clarifier to reposition the free floating bacteria to where they are most active; sand beds, surfaces of live rocks, and to biological filtration media. Ocean Direct provides you with a thriving, natural aquarium in minutes. Simply Perfect - Ocean Direct supplies the perfect union of physics and biology. Ocean Direct's Original Grade is Caribbean live sand with its natural particle breakdown; an overall fine material with smooth oolitic grains on the lower end of the spectrum, increasing to small bits of real reef rubble on the high end. This grade, rich in texture and soft color, is perfect for most any marine aquaria, but especially suited for burrowing fish and invertebrates eager to use the larget bits for burrow construction. This natural rubble also recreates the natural habitat of decapods, copapods, sponges and other natural reef foods. This is the product we use in our 120 gallon experimental reef tank, and it has performed flawlessly in a very high flow environment. This material often has reef rubble in it, but about 77% of the material by weight is less than 1 mm in size (most of that being smaller than .60 mm!) Learn More
