Heat Source for PLASTIC Tank

I have 2 Running Leg Frogs in a PLASTIC 10 gal aquarium. I received this as a freebie from my local pet store. They were going to throw it out but offered it to me instead. Can't resist anything free!! The light that came with it, however, doesn't put out enough heat for them. I have seen on several stick on heater pads "do not use on plastic setups" The temp stays about 70 - 75. Not sure on humidity but I mist daily, have been told this is good enough almost like a sub-saharan setup. Any ideas??? Or should I even bother??? I have included a few pics to help with ideas. (Liz- Before you say anything I know the stick on gauges are worthless. Will be getting different gauges for ALL tanks with tax refund money) Couldn't resist putting a pic of Solebum up too!!

Man... I want some running leg frogs....

Can you increase the wattage of the bulb or is it a tube bulb?

I have that same water dish for my cats.

It's a tube light. Took your advice and used a terra cotta dish for a flower pot in case they can't swim.

My local pet store has several for sale if you ever get this way!!

Michigan.. .Too cold for my blood....

You could try a human heating pad on low, and setting the tank on top.

Love your signature Kazooguyz2! Nice setup too.

I've got a 30-40 gal. ZooMed heat pad on the side of my approx. 32 gal. plastic tub. I put it on there at the beginning of December and the plastic hasn't melted or warped yet. I also have bubble wrap and tin foil covering about 1/3 of the top so all the heat doesn't escape. With the pad and the covering, it raises the temp. about 10 F.

A heat pad shouldn't melt it, as long as the plastic isn't too weak or thin. You could get one of the smaller 10 gal. heat pads and test it on a piece of similar plastic before you put it on your tank. ZooMed sells small pads that are said to be safe for small plastic tanks - it's called the Repti Therm Mini.
