Since 1972, CaribSea has supplied hundreds of public aquariums, zoos, aquaculture facilities, public and private institutions and hundreds of thousands of dedicated aquarists with the highest quality marine and freshwater 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 displays ever created. CaribSea recently celebrated their 35th year in business and their product line continues to grow.
