About Us

Why should you choose CaribSea Products?
At CaribSea, we take aquariums seriously. Since 1972, we have supplied hundreds of public aquariums, aquaculture facilities, and hundreds of thousands of dedicated aquarists with millions of pounds of the highest quality marine and freshwater substrates. CaribSea has been in the forefront of the principle of substrate as equipment, not just a decoration. CaribSea substrates are as precisely engineered as any piece of advanced equipment used by today’s hobbyists and professionals. CaribSea products are the chemical support, and biological filtation backbone, for many of the most spectacular marine and freshwater displays ever created. After over 30 years in the industry, our product line has expanded to include a wide range of unique products for reptiles, arachnids, ponds, freshwater and marine aquariums including a line of truly revolutionary additives. CaribSea is your aragonite source and so much more.
