So this might be a silly questions but I just wanted to be sure.
Using a large ultratherm (the 11"x17" model) on a small tub so that the UTH spills over the edges of the tub won't have any ill effects on anything, right?
Right now I'll be using a hatchling sized tub and I definitely don't want to buy a UTH for each tub size upgrade.
Thanks,
Dennis
