  • Every grain of sand in the ocean is covered with a biofilm. Nature’s Ocean® Bio-Activ Live™ Aragonite is naturally from the ocean. The bacteria on the sand are in a biofilm, therefore the bacteria are in their natural state, immediately removing toxic waste.
  • Artificially adding bacteria (or cultured bacteria) does not make the same biofilm. It is not as efficient as the biofilm found on sand in the ocean which have been naturally selected through millions of years of evolution. 
  • All bacteria on Nature’s Ocean® Bio-Activ Live™ Aragonite are preserved in their natural live state using a patented process and a patented saltwater enrichment solution QX-23™.
  • Nature’s Ocean® Bio-Activ Live™ Aragonite is guaranteed to contain more than 200 million live bacteria per pound of sand in a natural biofilm, ready to instantly start the cycling process and stabilize your tank.
  • Contains live marine autotrophic bacteria to provide proper inorganic chemical balance.
  • Contains live chemolithotropic bacteria.
  • Prevents biofouling.
  • Immediately removes nitrogenous waste (Ammonia, Nitrite and helps remove Nitrate).
  • Instant Cycling guaranteed

Beneficial Characteristics of Aragonite

  • Reduces harmful nitrate
  • Maintains proper pH
  • Provides enhanced buffering capacity
  • Provides essential inorganic elements such as strontium, cobalt, zinc and molybdenum
  • Approximately 0.5 - 1.7mm diameter grain size(Ideal for reef system tank bottoms)

Essential Trace Elements Provided by Bio-Activ Live® Aragonite

Zinc Sulphate, Calcium Chloride, Manganese Chloride, Cobalt Chloride, Copper Sulphate, Sodium Molybdate, Strontium Chloride, Nickel Chloride, Potassium Bromide, Sodium Silicate.

Rapid Cycling of Organic Compounds in the Newly Established Aquarium:

In the beginning of a newly established aquarium, waste products can quickly build up to toxic levels. Introducing fish, plants, and food to your aquarium begins a natural process called “Biochemical Cycling” which is exemplified by the nitrogen cycle.

The process begins when fish and invertebrates excrete waste which is added to the ammonia produced by decaying food and organic compounds. The more sources of fish waste, the quicker and greater the ammonia problem. 

Harmful ammonia and nitrite are constantly converted into less harmful nitrates, which in turn is used by plants and algae for food. An aquarium is full of both autotrophic and heterotrophic bacteria that want nothing more than to attach, grow, and form BIOFILMS where the bacteria convert toxic nitrogenous compounds and ammonia into harmless products.

Nature provides many types of bacteria that in the presence of oxygen carry out the oxidation of ammonia to nitrites and eventually to nitrates in a process known as nitrification. First, bacteria settle on aragonite (reef sand) where they grow into colonies and eventually form a BIOFILM. Marine nitrifying bacteria in the biofilm oxidize ammonia to nitrite. Then other bacterial species further oxidize nitrite to nitrate. Nitrate not utilized by plants is removed by other bacteria in the absence of oxygen (the anaerobic environment found in the lower levels of the sediment) in a process called denitrification. These bacteria are not harmful and are quite abundant in nature. However, three conditions are required for this process to occur:

  • A surface upon which bacteria can attach, grow, and form BIOFILM
  • Ammonia as the substrate to start the process.
  • An aerobic environment.


When you start a new aquarium with dry sand or gravel, colonies or beneficial bacteria have not yet had the chance to attach to a surface and grow. For a period of several weeks this presents a very hazardous environment for your fish. One has to gradually build up the source of ammonia (i.e., start with only one or two small fish) to allow time for the beneficial bacteria to grow and form a BIOFILM.

Now with Nature’s Ocean Bio-Activ ™ Live Aragonite Reef Sand, there is no waiting period or delay while waiting for bacteria to establish themselves. Both autotrophic and heterotrophic bacteria required for rapid cycling of the aquarium are already in their natural state - a BIOFILM on the sand particles. Nature’s Ocean Bio-Activ ™ Live Aragonite Reef Sand is fortified with a patented enrichment solution, QX-23 ™ , which keeps the bacteria alive, primed and ready to cycle harmful metabolic endproducts the moment it is added to your aquarium. Each pound of Nature’s Ocean Bio-Activ ™ Live Aragonite Reef Sand contains more than 200 million live bacteria in naturally-formed biofilms ready to biochemically cycle your aquarium and rapidly provide a healthy environment.

For Best Results Use as Follows:

  • Use a minimum of 1 pound of Bio-Activ Live™ Aragonite per gallon of salt water.
  • Setup filtering system and allow it to circulate.
  • During the first month, introduce no more than 1 inch of fish per 5 gallon of salt water
