Do a carbonate test just to be sure. All you need is vinegar.

Those rocks are fine for your tank. The carbonate test is just when you place the rock in vinegar to see if it has a reaction. If the rock starts to react to the vinegar, it's high in Calcium Carbonate which will affect the pH of the tank.

Carbon on the other hand is a chemical media that is used to remove impurities to help clear up water. It can also remove beneficial nutrients for plants and removes medication treatments.
