Geo-Marine: Florida Crushed Coral. It’s the only crushed coral with aragonite, which provides up to 25 times the buffering power of other crushed corals, dolomite or oyster shell. Eliminate chronic pH problems and provide maximum surface area for water purifying bacteria. CaribSea’s Florida Crushed Coral with aragonite allows an increase in bioload by up to 50% and it never needs replacement! Approx 2-5mm diameter (1/8–1/4").

This product is also able to be utilized in calcium reactors and plenum systems to deliver not only calcium, but also carbonate buffer, and essential trace elements such as strontium (up to 10,000 ppm!).

CaribSea Aragonite buffers to the highest pH and delivers more calcium, carbonate, and trace elements than any other substrate. Little or no rinsing required, aragonite keeps aquariums healthier, longer.
