At CaribSea we take aquariums seriously. CaribSea has been in the forefrom 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, your aragonite source and so much more.
