I cant seem to get the temperatures down with my uths on a 40gal and 25gal tank. I use my thermometer probe to check the temp and it reads around 100-101 on 40 gal and about the same give or take a few degrees for the 25gal. When i touch the glass with my bare finger its really hot. Ive tried adding more aspen bedding over the pad area to see if that would lower the temp but it doesnt. Would a thin towel placed over glass under bedding be a good idea? Also if you guys could give me suggestions on good uth controllers that will work with the zoo med brand. Ive read some reviews about the zoo med brand and heard alot more negatives than positives. Any help appreciated thanks!
