It is a highly concentrated, fast dissolving powder which increases alkalinity (carbonate hardness) and stabilizes the pH at the correct value. In these ways it contributes significantly to the health of all aquarium inhabitants including corals, coralline algae and fish.

Keep out of reach of children!
In case of contact with eyes rinse with plenty of water. Only for aquarium-hobby use.
Contains carbonate and bicarbonates. It does not contain boron since the depletion is different in different tanks and is not linked to alkalinity or carbonate hardness depletion.
