Gah i need your help with heating.

[pinkeye714]

I thought i had things right but i want to make it more right.
Okay, i have no pictures, i have 1 20G long tank and 1 28Q sterlight tub.
I bought Zoo Med Repti-Temp Rheostat at petsmart but i am not liking it much. I also got a UV 40 watt bulb light becuase its been cold in the house lately.

So lets see, i got 2 medium exo terra heat waves UTHs. Connected to the Zoo Med Repti-Temp Rheostat. The light i turn on and off in the glass tank during the night and day, though the light is not in the tub. there is a zoo med temp strip on the inside of the glass tank. I didn't put it, the tank came with it.
The temps outside and in the house lately have been 60F day and 43F at night.
the thank strip says 75-80 but that does not help me with the hot spot. plus i have a heater in the room.

I have only 1 hide in the warm side and i know i need another for the cool sides. But i feel like a fail here, can you please just tell me how to fix it. there are so many different things out there for the tanks, i do not know which ones are good, I cannot spend a lot of money on things, most i could spend is maybe no more then $40. So once again, i have 1 tub and 1 glass tank.

thank you
