Caribsea Crush Coral 15 #

Florida Crushed Coral is the only crushed coral with aragonite, which provides up to 25 times the buffering power of other crushed corals, dolomite, or oyster shell. It eliminates chronic pH problems and provides maximum surface area for water purifying bacteria. CaribSea's Florida Crushed Coral with aragonite allows an increase in bio-load by up to 50% and it never needs replacement. No rinsing required.
At CaribSea they take the aquarium hobby seriously. Since 1972 they have supplied hundreds of thousands of aquarists, public aquariums, and mariculture facilities with millions of pounds of the highest quality marine substrates. CaribSea substrates have become the backbone of today's cutting edge marine systems with a miracle mineral called aragonite. CaribSea, in an exclusive contract with the only aragonite mine in the world, supplies aquarists with 10 grades of aragonite "crushed coral." Now every hobbyist, from beginner to reef keeper, can enjoy this revolution in aquarium keeping.
