My vivarium is 23" x 15". In terms of an UTH, what size am i roughly best to go with? Is 11" x 11" ok? The only other size by this brand which is logical is the 6" x 11". Which would you say is the better choice? I was thinking of the ultratherm heat mat. Along with a thermostat by the same maker. It will be in a wooden viv, so will this, placed beneath the substrate, warm the whole tank correctly? I am getting a thermostat for it of course, i just wondered if it would heat the whole tank, or whether the opposite side will get very little heat.
