I've read so many mixed reviews on alfalfa pellets and was wondering why they make a bad substrate? I have started to mist his tank regularly with water, and am very careful about watching for mold. Other than it being dry I don't know if there are any other concerns about it, can you please tell me if there is?Yes. Your tortoise is pyramiding. Please read this thread on the same question:

You will need to read the care sheets at the top of the Sulcata section here as well as your setup will need some adjustments. The pellets, for example, make a terrrible substrate. Humidity has to be up, etc,etc. Please read the posts "pinned" to the top of this section and come back with any questions.
