I am using a bulb for heating, and the air temperature remains about 88-90 on the warm side of the tank, measured about 4 inches off the substrate, and about an inch in from the glass.
Same setup on the cool side of the tank reads about 80 degrees. I’ve read to use a UTH to help radiate heat upwards on the basking spot, if this isn’t recommended, I will just worry about the air temperature inside the tank.
Any thoughts on how I should proceed?
Oh and as a reference, I’m currently using a 20 gallon long tank since she’s fairly small still.
