Yeah I'm seeing if it will even out. It wasn't gunning anywhere near that high, that's only on the thermometer. One is an exo-terra and the other is a zoo-med. It's under the top tub, near the center of the tape. Where is the hottest place on the tape ?
It's a PVC rack made by a local guy. I'll look at some vision and iris tubs and see if they have any that would fit, thanks.
Edit: Turns out vision v-28 tubs are the same dimensions as the sterilite 28qts, so I'll order one in a few weeks and see if it fits.
