Buffer Block for Small Aquariums

Stabilizes pH, increases water hardness.

UltraClear Buffer Block pH Stabilizer.

The UltraClear Buffer Block will stabilize the pH and increase water hardness and alkalinity in your aquarium. Low or no buffering capacity (low alkalinity & calcium carbonates) causes the pH of the aquarium to become unstable resulting in wide swings of the pH.

The UltraClear Buffer Block adds essential calcium needed for healthy fish bone growth. It also enhances the growth and survival of beneficial bacteria for a healthy, beautiful aquarium. Great for snails!
