At CaribSea, we take aquariums seriously. Since 1972, we have supplied hundreds of public aquariums, zoos, aquaculture facilities, public and private institutions, and hundreds of thousands of dedicated aquarists and herp lovers with the highest quality products. CaribSea has been in the forefront of the principle that substrates are a piece of equipment, not just a decorative afterthought.
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, biological filtration, and biodiversity backbone for many of the most spectacular aquatic and reptile displays ever created. We are celebrating over 40 years in business, and our product line has continued to grow; making CaribSea your aragonite source and so much more.
