Tubs directly on flexwatt?

[yeroc1982]

That wont work, Needs to be directly ON the flexwatt. Snakes can pee/poop on the probe causing rapid cool down which in turns causes a heat spike.

Tstat probes never go in the tubs

Wow, soo confused. Some say inside , some say outside. So what is the best way so I can get the flexwatt nice and even?? Or can u put the stat probe on the outside, on the flexwatt but not in between the tub and heat?
