Here we go again with this..... IF you read the post, i say that i set my herp to X heat to get X heat on the hot spot... when 1 ROW of my Rack heat isnt correct, I measured the Tape/Heat strip (ARS has there heat tape in aluminum "plates/shelfs(iguess) ) And when it wasnt reaching the same temp as others, IT was Faulty, So i replaced? Nowhere did i say NOT TO Temp hot spot.... And If hotspot temp is wrong, Yes i will and should others Take the temp of the heat tape (if all tubs/husbandry is the same) Too see where the fault in tape is or if the strip is faulty.....
Maybe my no need for it in the tank caused you confusion because i did not word it 100% but it was a direct reply to PLACING the probe inside the tank, Which shouldnt be done due to water/urine/humidty messing with the hot spot.
This is again what I said
IR temp guns are good here, because this reason, If you set to 88, and its 94! as other said set to 84 itll be 90* Aslong as this is a constant you wont have an issue, Sometimes the tape will run a little hotter, I had mine set to 89, and it heated to 95 on 1 of the ARS levels, so i had to change out the level, Alot is dependent of the heat, tape. (i had 7 diffrent strips where youll likely have 1 looped in and out) So just lower Herps temp and IR gun the tape to get your hotspot correct.
So maybe your eyes arnt lying, but your also not reading everything. Im done responding to most posts your involved in as you like to harass or try to belittle.
