hello
I am in the process of converting an old 50 gallon tank that I have sitting around into a beardie home. It used to be a fish tank but when I moved from Boston to San Francisco a couple of months ago I tried filling it with water and it had a leak so Ireplaced it but want to use this one for a lizard. My question is if undertank heaters work. If I use a 2-3 inch playsand substrate will the heat be able to get thru? The heater I saw mounts on the outside of the tank on the bottom and supposedly keeps the temp 10 degrees above room temp.
Thanks In advance...
