Ok...lots of questions to answer since this weekend.

First off...I have holes along the entire top on one of the sides (both sides) as well as a "star" pattern. I have 2 big star patterns on the other sides at each end. (Basically each side mirrors the opposite side if that helps...The pics kinda suck sorry)

Second, already got bungee cords in place that wrap around the entire tub when closed to keep her from going on an (unplanned) adventure when I'm gone or asleep.

Third, I haven't had any problems with the cool side since I made the switch (still with only one uth on the warm side). It sits at about 80-83 degrees since I let it heat up (right after making the new tub).

Forth, I have been fiddling with the uth and thermostat settings and got it to stay at about 90-93 degrees on the warm side. I may however go back and do what was shown in the pictures yall posted and put the thermostat probe under the uth on the bottom of the tub and do more adjusting with the readings at the substrate surface like you recommended... and hot glue would prob be a lot better than tape since she prob wouldn't be able to move stuff around...Thanks for the tip!!

Thanks for all your help guys!!! I really appreciate it as this is the first time i've done something like this before.
