i agree, the 93 is high and i would like to bring it down. that's why i love the idea that deborah has! and it's very convenient too because i'm about to buy a new, larger UTH for the glass tank i'm getting so i can use the old one for the cool side! and i have a spare T-Stat too. and thank you piedlover79! i was worried because i thought that she would end up getting an RI or something, so i'm glad it isn't as bad as i thought.
