under tank heat mat

I was wondering which ones people thought was the best to use to add just a little heat to the tank. Without a heat lamp my tank is is about 75 degrees. with lamp its about 80 degrees. im housint Emp's by the way. I know not to use them under the tank. I just wanted to add a little heat for when it starts getting colder where my set up is gets chilly at night in the winter.

For my brother's old iguana tank we used an Exo Terra HeatWave mat and that kept it nice and warm in there. I'm not too sure how different mats are measured in terms of performance/output but I don't think you can really go wrong here.

ok thanks. i was looking them up and i found a few different ones and wasnt sure if one was better than the other. and thank you for being the first one on 3 forums to actually read what I wrote and tell me not to put a mat on the bottom of the tank. thanks

not on the bottom, do the sides

I know not to put mats on the bottom. I was asking if there was a Under tank heat mat (which is what they are called) that people preferred.

No problem, man. Glad I could help.
