Al - I deleted all the readings that I felt were wrong, but it spiked up to 88-90 degrees when it was really 75 degrees. I run my fans and my heater based on temp to keep the tank at 77 degrees. There is a program you can use that builds in a bit more safety (prevents the boiling or freezing of fish -hehe). I can find the link where I just read that if you want it. If you are using a chiller, I'd pay close attention to this. I don't use a chiller and I use an undersized heater, so I think the worse thing that would happen in my tank is that the fans don't come on if the tank gets hot. I also have the Reefkeeper on this tank, and I think this just made up my mind that the MHs are staying on it. I already have that set with a temp control (using a different temp probe) that shuts the lights off if the temp is too high. What I am doing with the ACJr (fans/heater setup), I couldn't get to work on the Reefkeeper. I think all the controllers have some limitations. However, I am still glad I have them. Actually, I am glad I have BOTH. You might consider the higher end ACs.

Woody - There is a 90 day warranty on the temp probe, and Neptune has already responded that they will replace it.
