Cool this has me puzzled.

Your pics aren't very clear, but it looks like you have different ventilation holes in your tubs. You may be getting more air circulation in some which would give you different temps.

Good thinking. I switched the tubs around and am waiting to see if that will make a difference. In the mean time i'm going to run to the store and get a couple more tubs to make the holes uniform. Thanks for the help guys. I'll check back to let you know.

okay. All of teh tubs have the same number of holes and the holes are in teh same position. I tried switching the different tubs around to see if that was it but the temps are still fluctuating. I checked on it an hour ago and the temps were 93 on the top, then 95, 91, 90 going down the rack. I just checked back and they were 94, 92, 90, 91. This is really getting frustrating. I moved the probe to directly on the heat tape to try to keep the one below 95. The room temp is staying constant, I really don't know what could be wrong here. Anyone else have any idea what could be happening?? I want to get this straitened out ASAP!! :confused: :confused:

Everything I've read says that racks tend to be a bit warmer at the top due to hot air rising. One breeder I asked about it told me that he keeps males in the cooler bottom tubs or doesn't use them at all. Also, while you are experimenting, keep in mind that the heat tape takes several hours to stabilize so checking every hour may give you inaccurate temps.

thanks for the tips. I'll keep that in mind when I check next.
