Aquarium Live Sand for Marine Fish and Reef Tanks - Nature's Ocean

Compared with dry sand, live sand can be expensive…but if you must get your aquarium up, running and filled with livestock immediately, it can be a time-saving product.

Benefits of Nature’s Ocean’s PATENTED Bio-Activ Live® Aragonite Aquarium Sand:

The sand is a natural denitrifier in that it will help to control the buildup of this waste product in your aquarium. I have seen nitrate levels drop by half in as a little as two days after live sand was added. It is also a great way to inoculate a new aquarium with nitrifying bacteria. And, if that were not enough, live sand will also help maintain your pH and alkalinity levels!

Aquarium Filters & Filter Media: Live Sand as Refugium Substrate

remove toxic wastes from saltwater aquarium tanks. Live sand helps speed the natural nitrogen Seawater liquid that is in the package into your aquarium tank, this liquid is used to help preserve the Live Sand in storage and will help with the instant cycling of your fish tank.

Live sand in a freshwater aquarium

United Sates Patent No. 6,376,229 issued on April 23, 2002 for a new method of preserving marine bacteria. Using the patented method Nature’s Ocean® harvests and packages live sand with an optimal amount of water and air in retail packaging specifically dimensioned and configured for maintaining ammonia oxidizing bacteria in a state wherein the bacteria are capable of metabolic and physiologic activity in excess of twelve months at room temperature. When introduced into an aquarium Nature’s Ocean® Bio-Activ Live® Aragonite Reef Sand instantly begins the cycling process which provides an optimal environment for marine life.If you have a sand bed that is at least 6 inches deep, you have what is called a deep sand bed. The advantage of having a sand bed greater than 6 inches in depth is that it is so deep that oxygen can’t get to the bottom layer of sand. There are bacteria that actually remove nitrates from the water that live in those anoxic (oxygen free) depths in the sand. So, an aquarium with a deep sand bed (either in the display or in a refugium) can not only turn ammonia into nitrites and nitrites (in accordance with the nitrogen cycle), but it can also remove that nitrate from the water column altogether (denitrification).Biological filtration, in a saltwater aquarium, is performed by bacteria that grow on the live rock and on the live sand in your aquarium. Aquarium sand is a substrate with a lot of surface area and creates a perfect home for those biologically beneficial bacteria to grow on. But that doesn’t mean that you have to have a sand bed to have a good biological filter. Plenty of aquarists are successful keeping reef tanks with absolutely no sand bed at all. These tanks are often referred to as bare bottom tanks. But plenty of life will inhabit your sand bed if given the chance. In 1993, at the Marine Aquarium Conference of North America (MACNA), shared an idea that was new to the majority of American aquarists. This idea, which had been employed by European aquarists for many years, was to place sand on the bottom of the aquarium — not just any sand, but sand that is taken from near a coral reef, kept damp in seawater and placed directly into the aquarium. It is referred to as live sand, because it contains its original micro- and macro-fauna.
