htyplatinum,
You've gotten great advice all the way around on this great forum. Based on the multitude of feedback, I am changing my recommendation and advising the crushed coral. Let your LFS know that this is the direction that you want to take and ask for additional / personal guidance on its application. If they are knowledgeable, they won't steer you wrong. If they recommend a buffering product (as did I), be firm and let them know that you would prefer to do this "without" chemicals. The others here are "right"!!! Only go with the more unnatural recommendations (like the one I gave you) if the majority advice has been attempted and hasn't worked.
Crushed coral for you, my friend, and "best wishes"!!! It is absolutely great advice from experienced keepers who have been here before.
