What are some good rocks to raise pH and hardness?

I am looking for rock that would raise the ph and hardness slow enough that the fish would be able to adjust without to much stress.

Hi aaron, Hope you don't mind, I moved your thread to a part of the forum where it should get the attention of the members who are knowledgeable about pH.
