Catching their Food?

Not to hijack the topic but, do you have a website from which I can order such a heater?

Personally no. But you can order them from Petco or Petsmart's website. I'm pretty sure lllreptile also sells from them. I just buy my mine at pet stores.

Sorry to keep on - but how can the heat radiate up through the substrate thats around 4 inch thick??

It can't. Mount the heating pad on the side of the tank. And keep it away from water. Water hitting the side of the tank where the heater is mounted can cause a thermal crack, possibly shattering the glass.

Arr thanks Kurt - that makes more sense. I've stuck it further along from the water bowl, on the side of the tank. Many thanks.

[Kurt]

You're welcome.

Undertank heaters work just fine under the tank. I've used them for years with no problems and have always provided a good source of heat.

Has that been with a wet/moist substrate?
