Cant get my tank to stay the same temp and humidity

[bcr229]

I ordered a heat pad a few days ago, it will be here in a few hours.

A heat pad should never ever be used without a thermostat as unregulated it will get hot enough to burn and kill your snake.

If you have a 20-gallon tank with two heat lamps you're likely running it too hot already unless your house ambient temp is about 60*F. I would turn off the "day" lamp, run only the red lamp on a thermostat, and cover the rest of the enclosure top with foil to keep heat and humidity in the tank.

At some point your snake will outgrow that tank so start saving up now for a proper reptile enclosure, not just a bigger fish tank.
