I almost threw away a bunch of money this past week or so.
Some of my coral haven't been looking their best recently. Not as in dying off, just not as plump and thriving as I'm use to. I thought maybe it was vanadium(maybe is still part of it) levels being high.
2 days ago the oddest thing happened. Suddenly my inkbird alarm went off, saying my tank was over 82 degrees. I'm freaking out, can't figure out why, and then suddenly it goes back down to normal. Did it again yesterday, I can't figure out what is going on.
I figured I would give it a good cleaning before buying a new inkbird, assuming it was going bad.
Turns out, my temperature probe wasn't where I thought I put it. The temperature probe I thought was the inkbird probe was actually a temperature probe for my ph probe. My inkbird temperture probe was in the section with the pipes from the overflow, not easy to see.
It had come out of the water barely. The temperature in the cabinet itself was apparently around 77-78 degrees. So it was kicking the heater on, but not low enough to set off the low temp alarm. The high temp alarm was going off because it apparently got just wet enough from the actual water to give a degree, but then it would quickly go back to what I thought were normal.
Moved the probe to where I thought it was, and made sure it was under water. Tank temp was 83 degrees.
That could have gone much worse very easily.
