Wow, THANKS EVERYONE!!! Very helpful and very prompt.
I've already done the foil and moved the probe underneath. I'm going to be putting a new layer of substrate tomorrow as I've had this batch on for a month at this point, and will copy every detail of the setup in that thread, in addition to getting some fake plants for cover.

Bcr, I remember checking out PVC enclosures on this one website while browsing through these forums...they looked very solid and I was planning to get one eventually, but due to the cost it might have to wait a few months...No plans on getting any more BP's for now, although I REALLY like BEL's and mayyyyy get on in the distant future. Can you perhaps refresh my memory of the website I stumbled upon? All I can say is that those tanks looked very....zoo grade? All good if not.

They looked like the ones that this guy uses: https://www.youtube.com/user/viperkeeper
