Until now there was no alternative to the live rock. Then came the LifeRocks from CaribSea. Fossil aragonite rock with a bacterial coating that shortens the cycling even compared to live rock and creates a long-term stable microclimate. And all this without ecological concerns, with a lower nutrient load and an incredible freedom of design. CaribSea LifeRock Originals are left in the shape and size as they occur in nature. This unique variety of shapes means you will find exactly the stones you need for your individual reef construction. For example, the rocks can serve as a base, supplement or stabilize arches. Furthermore, you can combine the rocks with suitable composites to create your own creations and shapes.

The LifeRocks of CaribSea are aragonite rocks of fossil origin, which are extracted from dry reefs. Formed by nature, no stone is like the other. Every single one captivates by its very own character. This makes LifeRocks ideal for building spectacular and individual reef Aquariums.

Even though few people say it out loud: the amount of live rock available on the market exceeds the amount that can be legally extracted. LifeRocks are extracted sustainably and guaranteed without destroying existing ecosystems. Therefore the use of CaribSea LifeRocks as an alternative to live rock is an active contribution to environmental protection.

LifeRocks are coated with a reddish bacterial film. This gives them the appearance of live rock with a calcareous red algae coating. More importantly, however, LifeRocks become revitalized live rock through the bacterial coating. The biofilm, which consists of permanent stages of different bacterial strains, enables transport and storage in a dry state. Aquascaping also offers completely new design possibilities: You can fully concentrate on the construction without having to take care that the stones do not dry out.

As soon as the LifeRocks have arrived in the water, they come to life. This makes them more than just a visual eye-catcher for fascinating reefs - they are a reef that lives and filters and offers invertebrates, corals and fish the optimal microclimate. The cycling period can even be shortened in comparison to live rock! And all this without any uninvited guests. This makes the LifeRocks of CaribSea not only optically an alternative to live rock, but also functional!

The extraction of LifeRocks from fossil reefs makes them perfect not only on the outside. Their chemical and structural composition is also natural. LifeRocks are absolutely silicate-free and do not bring any other chemical surprises into the water. In comparison to live rock they also show a lower nutrient load!

The aragonite rock has grown within a functioning ecosystem. The high macro- and microporosity has developed naturally and provides exactly the structure that microorganisms and invertebrates are used to and need from nature. This makes a stable, colourful and healthy ecosystem from microorganisms to shimmering fish a breeze!

LifeRocks are pre-infused with bacteria that lay dormant until the rocks are placed in the aquarium, which allows for dry transportation and storage. Once activated, the bacteria work to bring the ammonia levels in the water down to zero. The result is a living, breathing reef that creates the perfect microclimate for marine life.

Available in a range of shapes and sizes, LifeRocks meet all your aquascaping needs. LifeRock Original, for example, is a versatile product that can be placed or stacked in simple and complex configurations for outstanding biological filtration. Shelf Rock and Arches enable you to create spectacular caves, ledges and arches, while Belize Branches mimic the look of stony reefs. The LifeRock Shapes, Arch, XL Arch, Mega Arch and MegaCave provide you and your animals with arches, rings and tunnels that optimally recreate natural Habitats. Life Rocks can even be broken up and added to a refugium, sump or overflow for extra filtration.
