my cool side temp stays at a temp of 78.6-79.9 degrees is there any other way to get it to the mid 80's (82-84) without using heatlamps and whatnot?? my warm side gets to 94.6 sometimes up to 95. im also using a 20 gal tank with an ultratherm heatpad purchased from rich at reptile basics.

any and all suggestions are welcome and i thank you in advance.
