Crushed coral 1 Ltr

Crushed coral is a natural calcium carbonate material used in aquariums to raise and stabilize pH, increase carbonate hardness (KH), and add essential minerals to the water.

How Crushed Coral Works

Buffers pH: It dissolves gradually when water becomes more acidic, neutralizing acids and preventing dangerous pH crashes.

Increases Hardness: It adds calcium and carbonate ions, which raise general hardness (GH) and carbonate hardness (KH).

Ideal Environments: It benefits African cichlids, saltwater reef tanks, goldfish, and freshwater tanks with soft, acidic source water or snails needing shell support.
