The Nature's Ocean Premium Atlantic Crushed coral is 100% from the ocean floor. The natural crushed coral substrate maintains superior pH, and marine chemical balance. It also provides maximum surface area for biological nitrification. Scientifically graded for uniformity, which provides maximum water flow and aeration, preventing anaerobic dead spots in the bacteria bed. Completely chemical free, and pre-washed (minimum rinse required). The Atlantic Crushed Coral with Aragonite #4 comes in a 20 lb. bag.
