So, just for more information so you guys can make more informed decisions based on my specific situation. I keep my ball in my living room. The tank sits a few feet away from a large window which provides pretty constant sunlight throughout the day. My apartment temp usually is on the low end at about 70-72. My aquarium is a 10gal that has a layer or reptile carpet and then about and inch to inch and a half of ecoearth. My UTH is stuck to the bottom of the tank and my tank has risers on it that helps air flow underneath and this sits on a solid wood surface.
