Great info Tim... Will you see a physical difference on the surface of the rock or water color???

I removed alot of "dead" particles from the rock when I got it. It's been in the tank for a week. I notice alot more debris on the rock after the first week. Alot of it had turned white (almost like ash all over the rock). Yestday I did about a 33% water change and "dusted" off the rock. The water almost had somewhat of a greenish tint...

Today the tank looks (and smells) better. I plan I doing a water test today to see how it's coming.
