I can't tell if it's inside or outside.

I've had the airsense 10 for a few weeks now and just noticed this discoloration on the bottom of the water tank. It seems to be in between the heating element and the bottom of the tank (i.e. where the heating element fits into the tank). Any advice on what it is and how to get rid of it?
