Here in Humbleville, USA we make a lot of mistakes.  They are some of the best learning experiences we can get, so we relish them (so long as they aren’t continually repeated mistakes).  While cleaning up the fish tank and doing some water tests, the read-out end of our water tank thermometer plunged into the tank.  At the time, I didn’t think anything of it.  Plucked it out, wiped it off, and went about my business.

About a week later when I wanted to check the water temp to make sure the heater was still working, I discovered the thermometer was no longer reading the water temperature.  More than just a dead battery, the water had caused some slow oxidation within the display unit.  Yikes!  No wonder it wasn’t working.

Lesson learned:  Check the aquaponic equipment frequently if not daily.  Cheers!
