Florida Crushed Coral 40 lb
Florida Crushed Coral is a natural aragonite-based aquarium substrate designed to raise and stabilize pH and carbonate hardness (KH). The larger 40 lb bag is ideal for large aquariums, full substrate builds, or multiple tanks, especially where hard, alkaline water conditions are required.
Its coarse texture makes it perfect for African cichlid aquariums (Malawi, Tanganyika, Victoria), as well as brackish and marine systems. Crushed coral can also be used in media bags inside filters or sumps to provide controlled, long-term buffering without replacing the entire substrate.
