Ok, someone sugested that I get a small aquarium heater to heat my 10 gal terrarium. Well, I did, and put it in a glass of water (covering the heater to the fill line only) and well, it only raised my temps by about 2 degrees or so.
Now, I have a much larger aquarium heater, but I can't find the room to lay it down flat, and can't find a glass jar big enough to fit it in.
Any ideas? Something I am doing wrong?
(BTW: the small heater is a small $7 cheap job from Wally World)
