I am a little confused about my heating situation. I can't seem to get my temps up (according to my thermometers) but my girl is only staying on her cool side.

Right now my accuweather says the hot side is at 80.4 and the cool side is 77.2..which is too cold on both ends, so i can't figure out why she isn't going to the warm side.

let me give you some basic info. I have also included pictures of my set up.

-29 gal glass aquarium
-repti-bark substrate about 2-3 inches thick
-accuweather thermometer and old flukers 2 in 1 I am still using.
-2 identical log hides ( i know not the best , I am working on something new)
-I have two of the smallest zoo med heat pads on her hot side. they go out about half way
-on the cool side I am also using the smallest zoo pad, but it was an old one so It won't stick on the bottom and doesn't provide much heat.
-I have a 75 bulb on the hot side
-my house temp is about 65-70 degrees right now
