A beautiful piece of nature at home: Create your own unique reef aquarium!

Do you dream of the dark blue shimmering Maro Reef off Hawaii or the colorful Rainbow Reef of the Fiji waters? With the multifaceted selection of Arag-Alive!™ substrates from CaribSea you can make your dream come true and recreate the world's most beautiful reefs in your home. The unique sands of CaribSea were developed in cooperation with public aquariums and zoos. Six environment-friendly composed bottom substrates make every aquarium a real eye-catcher. Arag-Alive!™ accelerates the cycling phase of your aquarium, because thanks to its special marine bacteria you will establish a stable biological balance in your aquarium in a short time.

Whether crystal clear, cheerful pink or volcanic black shimmer - CaribSea Arag-Alive!™ provides you with a spectacular selection to make your individual aquarium dream come true. The six different types of sand come directly from the natural reef ecosystem, where they are extracted in an environmentally friendly way. Arag-Alive!™ is ideal for both beginners and professionals. Choose from different reef ecosystems and authentically recreate the respective habitat. With coarser grains you also offer your digging animals a species-appropriate home. The unique color variety of the near-natural substrates as well as the different grain sizes enable you to create extraordinary water worlds.

With CaribSea Arag-Alive!™ substrates you can quickly and safely create a stable reef ecosystem. This live sand is much more than just beautiful, real reef sand. With over 400 million bacteria per bag, you will run your pool with a wide range of natural marine bacteria. Arag-Alive!™ sand helps to control the dangerous ammonium content and even reduces nitrite and nitrate levels in the water. Living stones can settle in faster and grow better. Arag-Alive!™ from CaribSea also contains other specially bred strains of marine bacteria. Innumerable heterotrophic, autotrophic and chemolithotrophic bacteria help in the running-in phase and still long beyond. The excellent biological activity of the substrate is also confirmed by independent laboratories.

Aragonite is found as a purely natural product on the Bahama Banks, where it is formed during the metabolism of algae and bacteria. It precipitates as a result of a biochemical process and floats above the Bahama Banks, where it sinks to the sea floor. Every year, almost 2 billion kilograms of new aragonite are created in this way. In the natural form we offer, aragonite is a thoroughly sustainable product.

With aragonite sand you create the best conditions in your saltwater aquarium so that its inhabitants feel well, thrive and stay healthy. Because it has something decisive which calcite or dolomite do not have: Its natural oolitic (egg-shaped) grain makes this sand pleasantly soft. This makes aragonite sand suitable for digging animals such as gobies, crabs and sea cucumbers. But also hard corals and "difficult" plants, such as tall sea grass, grow particularly well in it. The natural, round polished reef sand is perfectly suited for method of the "Deep Sand Bed" (DSB).

The highly porous aragonite is available in various grain sizes, with the smallest grains being less than one millimeter in size. These tiny grains of sand offer the great advantage of more surface area for bacterial colonization than other sand. Aragonite in a cube of one cubic centimeter has a surface area of an incredible 8000 square meters! That much biomass means that aragonite is unbeatable in the reduction of nitrates, nitrites and ammonia.

Experts repeatedly stress the importance of aragonite as a substrate. As in its marine home, aragonite also comes into action in your tank as soon as the pH value falls below 8.2, the value of natural seawater. This is because when the water becomes acidic, the substrate dissolves, releasing minerals and trace elements such as calcium, strontium, magnesium and iodine. Corals absolutely need these substances to form their skeleton. The pH value then returns to normal and your aquarium remains stable. All natural and without chemical additives. This is one of the many advantages of aragonite over calcite or dolomite.

Only aragonite can do this too: The "miracle mineral" has a 30 times higher filter capacity than purely decorative sand such as calcite or dolomite. Anyone opting for sustainable aquaristics chooses aragonite from the very beginning. In contrast to other substrates, you hardly ever have to replace real reef sand and you save lime water and calcium reactors. Just add a little sand if necessary and enjoy your unique stable ecosystem in the aquarium.

On the sandbanks at the coral reef you can see the fascinating cycle of nature: they are constantly forming new ones. Aragonite from CaribSea comes exclusively from self-renewing sources (Bahama Banks). Here the sand is extracted in an environmentally friendly way and comes to your home free of heavy metals, pesticides or other pollutants, but full of good and natural substances. Use sustainably extracted sand from intact reef ecosystems and start with the most natural substrate in the pool. For the love of nature. For the love of your hobby, seawater aquaristics.

Aragonite sand from CaribSea is available in many particle sizes. Choose the appropriate grain size and composition for your aquarium and thus recreate the chosen habitat as authentically as possible.

By the way, it is not true that aragonite blows more strongly with the current than calcite or dolomite. The degree of blowing is equally dependent on the grain size of all substrates - the lighter the particles are, the easier they blow.

CaribSea offers you a wide range of aragonite sands - from very fine to particularly coarse grain sizes. The bandwidth ranges from 0.25 mm to 50.0 mm. Simply choose the optimal solution for your habitat and tank size.
