Stupid, fluctuating temperatures..

You dont really need two that or get something similar to what I sent you above so you can try to tone down the temp on the other size to 70. You wanna keep the cold side around 70. I would be in a 20 gallon one on the left side in the middle would give you the temps yo uneed

70 is too low. I would say 75 is the absolute lowest you'd want to go in a glass tank. Most people keep their cool sides around 80, which is fine.

My temps in my racks for my bps and geckos are 92-96 hot spot, 78-82 cool spot. I generally give my animals a slightly higher hot spot temp but give them room to regulate.
