Placing it on the probe itself can cause the probe to be insulated causing you tstat to maybe not work right.

The substrate over the heater needs to be no deeper than a quarter inch. The rest of the tank can be as thick as you like it. Mine is about an inch and a half.
yes my pad is stuck to the bottom of the tank on the outside ofcorse , and yes there is a bit of room for the cord to come out but not nearly enoph space between the table and the bottom of tank for a sensor the size of a aaa battery. thank u very much for the help, but your reply is very confusing are u saying not put glue or tape directly on the probe ? i wouldn't do that i was going to glue the suction cup down
