Yes. If your rocks are actually limestone, they are the cause for the pH elevation in your aquarium water. Limestone is calcareous (contains calcium) and is known for its ability to both harden the water and increase the pH.
People also ask, is limestone harmful to fish?
Actually no, it is not harmful to the fish. But yes you should know what pH is required by your fish. If it requires a low pH, then it is not good to place limestone in the fish tank.
