im having the same problem minus the cracks. I have been soaking my rocks for WEEKS and the ph is still off the charts. I also don't fully understand the ammonia process. Can't you just put the rocks into the tank when or if the ph goes down? It's an already established tank. Is the ammonia just for new systems? It seems like it would cause a spike if you put it into an established tank. (but again i don't fully understand it) am i wrong?
