so, an undertank heater on one of my vivariums blew out or something. The heater is attached to the bottom of the tank. The tank is a 40 gallon, with expanded clay bottom, gravel, substrate, water and other stuff in it. The new heater is an exo terra undertank heater that requires me to put spacers under the tank. I and a friend together cannot lift the tank at all. SO, how can I lift the tank enough to get the old heater off, put in the spacers, and get the new heater on, WITHOUT disturbing the tank. let me know. Thanks.
