Swap probes to the other tub and see if same situation happens. If does then its how your have it set up
I have both of the tubs at more or less the same temp now. I raised the tub up a little to get some air to the probed UTH. After it cooled a little and the herpstat started giving it more power, I just waited for the other tub's temps to raise to the correct level then I dropped it back to normal position. Now I'll just leave both tubs in the same position and hopefully the temps will remain stable!
