ok, i placed a piece of foil over one side and got it back up. do i need to mist the tank to keep the moisture in there, or what? im using douglas fir bark, it is what came with the setup i bought. is that not very good? they also steered me away from the under the tank heaters?? dont know why though. with the under tank heater, will i still need the top lamps? do the heaters come with a thermostat or how do i do that part. im sorry to be asking so many questions, im just new have spent alot of money already on this for me to do something wrong and have something happen to him.
