What are the temperatures in the tank, sounds like you have no thermometer to check temps?

a 75 watt bulb just might be too hot in a 10 gallon tank, but unless you have a thermometer there's no way we can help you.

Ball pythons won't digest well if there's not enough heat, and will digest extremely well with the proper temps.

Sooo, what are the temps in the tank, no guessing, lol.
