Crushed Coral- Raise Low pH and KH Aquariums - Calcium Carbonate - 4oz Mesh Bag

A mesh bag of a RANDOM COLOR, containing 4 ounces of crushed coral. Crushed coral helps to buffer pH, increasing it from low acidic water such as 6.0 pH to more stable pH such as 7.0-7.8 pH.

Crushed Coral buffers kH which leads to more stable water parameters and it also provides a source of calcium and carbonates which is highly beneficial for aquatic species such as Neocaridina shrimp, ramshorn snails, bladder snails, mystery snails, guppies, mollies, and platys or any fish that likes hard water with minerals in it.


Crushed coral provides calcium and trace minerals these animals need for shell, exoskeleton, and overall health.

Crushed Coral is among the safest methods to buffer pH and KH while also providing calcium and trace minerals to your tank without causing a stressful pH spike that could be fatal for your fish. Crushed Coral takes 1-2 weeks to take effect.

Natural, Long-Lasting, Low-Maintenance.
