Hi there. I'm new here and just acquired my first ball yesterday and I'm trying to get his new home set up. My question is, I cannot seem to get the temps quite high enough on the cool end of the tank. I have a 20g long critter cage, and 3 under tank heaters designed for 20g tanks. Temp on the cool side is right above 70. Temp on warm side (and right under basking lamp) is just under 90. What am I doing wrong here? For bedding, I've got reptile carpet and then aspen on top of that. Also, I have covered the screen top with foil and taped it down. Humidity is around 70%.

We keep our house on the very cool side, so would I be better off with a ceramic heat emitter or something? These uth's just don't seem to be doing the job very well. And I've tried a rheostat and it made no difference.

I would love any input from you experienced keepers! I want my little serpent to be happy!
