I've posted before on this but nothing has worked so far

I have a 29 gallon tank with a uth on the back rated for a 50-60 gallon tank. It's insulated with tinfoil on the back and sides. The uth is covered by a sheet of cardboard and then a 1 inch thick sheet of styrofoam that covers almost the entire back. The lid is covered in tinfoil as well. And my heat is still way too low!!
During the day with the light on it gets pretty close to 80 but at night it drops. I just got up and turned the light on and I'm reading 72.
How the heck do I fix this? I really can't afford to go out and buy expensive equipment. Would a heat lamp help? How can I get my heat up? Are my crabs going to die?
