Dr del,
So the UTH should only take up one half of the entire bottom of the tub?
Because literally, this 24w large takes up almost the entire base of the tub where the snake crawls.
directly touching the plastic where the UTH is on the floor of the tub, my thermometer sensors states its 92 degrees (ouch)
I'm using just paper towels, ovelapping each other, so its slighty warm on the top.
edit: I will post some pics of the current tubs here in a couple of hours, busy doing work at home right now
maybe yourll be able to see for yourself, ill take pics of all angles and what not
