ok so have my 4 standalone tubs over a 3" piece of flex-watt running on a helix dbs1000 thermostat. have had temp set at 93 all day and my temps have been slowly moving around from 90-94 and one tub for some reason got up to 96-97 at a few points. i have the accu-rite thermometer probe in the same spot on all my tubs. so heres my HUUUUUGE problem right now and im pretty pissed off. well i was holding one of my babies and put her back then went to take out another and noticed two little spots of blood. well i take him out and search him all over and it looks like her was getting burned or like a split very small but it was there. whats going on. i just doubled up my paper towels, turned the thermostat down to 90 degrees and have taped down a probe from another thermometer to the flex-watt to see what its saying. and right now it is actually saying its 3 degrees over what my thermostat is set at.

do i need to put a piece of tape over the whole thermostat probe covering it entirely so it doesn't get touched by the open air since these are just on a shelf in a room that is around 73-75 degrees?
