    New Apex Jr. temp probe issue

    I've been running a new Apex Jr. without issue for about a month on a QT tub with just an LED light and a heater. I moved the Apex Jr to a reef tank, plugged it into a different wall outlet and now the temp probe is bouncing around between 78.1-78.5 and back down. I have a MH light, heater, and fan set up on the Apex Jr., all basic programs. I added the fan when I moved the Apex to the tank. It wont stay settled on a temp, just goes 78.1-78.3-78.4-78.5-78.4-78.3 and so on and so forth. I have unplugged the system form the wall outlet, let it sit for a few minutes and plugged back in. It comes on and settles just fine like its working well, within 10 or so minutes the temp starts bouncing between back and forth as described above. Any thoughts on what might be the problem?

    Turn off all your outlets.

    See if the temp stabilizes over the course of 30 minutes.

    If it's stable with no outlets turned ON, something is causing it t be erratic..just need to figure out what.

    Turn on one outlet, doesn't matter which one

    See if there's an impact to your temp probe. Repeat the process.

    By "off" do you mean each outlet is in the off position in their programming? Or do you mean wipe the program completely so there is no code?

    Just turn them OFF. You want to see if any devices are causing the problem so you're going to turn them on one by one.
