Another question: The media -- meaning the sulfur, crushed
coral, and carbon; do they need to be changed, and if so how
often?
Thanks!

The sulfur is used as a food source for the bacteria- eventually it will need to be replenished, but not for a Real long time. The crushed coral will dissolve slowly and will eventually need to be refilled (the pH out of the sulfur is below 7.0, so the coral-chamber acts like a mini calcium reactor). Again, that will take a while. The carbon should be replaced every month or two IMO. Over time it will lose its ability to remove the hydrogen sulfide.
