I did try the magnet idea and you are CORRECT! It didn't work! The lead balls will NOT stick to the magnet. I just removed all the fish, parts of the sand bed, the best I could, running carbon and began a series of water changes.

The manufacter of these thermometers say that the very bottom of the tubes are made up of small parts of metal balls (to help sink) and lead balls.


Thank you for posting!
