Crabitat humidity and temp (cold weather)

[BlookittiePC]

Re - insulating a tank with under tank heaters mounted on the sides or back. If it's a Ultratherm (which you attach to the glass with electrical tape), you can put insulation over top of it. If it's a Zoomed (or one that the actual heater is sticky), you can insulate around it but not over top of it.

This is exactly what I use on my hermit crab tank

You can find Ultratherm uth at reptilebasics.com or beanfarm.com. they are a bit pricey but work really well. The sticky ones you get in the pet store just don't generate enough heat. Get one that covers the back of your tank from the top of the substrate up. And you can insulate them. You can use reflectix tape. You can find it at home depot. Oh, and you tape the ultratherm to the tank. Bulbs will dry up the humidity as you've seen. Seal the entire lid with saran wrap. And you csn cover the tank with a blanket.

Mine wasn't making enough heat so we got the bigger one and added it. Both the heaters together make it warm enough in my ten-gallon.

I always go with whatever size UTH will cover the most area on the back of the tank. On my 10 gallon isolation tank I have an 11 x 17 zoo meds that covers almost the entire back. I believe that it is called out for a 55 gallon tank. Not a 10-20 gallon.

Don't forget most manufactures are selling UTH heaters for reptiles so they can have a "warm spot" to lay. Hor our crabs we use the heaters to try and heat the entire air space inside of the tank so you will naturally need a larger heater to cover the larger area.

With having a larger heater you may need to purchase a thermostat to hook up to the UTH so it does not overheat the tank.

I now have two heaters on the back and one on each side. I went more by sizes that would fit, rather than the size that it was supposed to heat. Two are Zoomed and two are Ultratherm. Yes, putting insulation OVER a zoomed is a fire hazard. Like someone said, Reflectix can be used, or some people use cardboard covered in tinfoil I believe.

So i can only put reflectix on ultratherm or flukers heat mats?

Yes. Any others insulate around it.

So I can put reflectix tape only around it? How would that look?
