Since 1972 CaribSea has supplied product to virtually every major public aquarium, marine zoo, aquaculture facility, public and private institution as well as hundreds of thousands of dedicated hobbyists worldwide. Caribsea’s substrates are as precisely engineered as any piece of advanced equipment used by today’s aquarists with task-specific mineralogy, sub‑millimeter grading and advanced coatings as standard. CaribSea products are the chemical support and biological filtration backbone for many of the most spectacular aquatic displays ever created.

There is simply no other supplier that we look to when it comes to substrates. They have been the gold standard for many years and their recent developments in the dry rock area have been very exciting to see.
