Thermometer broke in my tank

[bluecheese]

I just heard a popping noise coming from the tank. I looked over and saw the metal beads falling into the sand bed. How much of an issue is this? Do I need to painstakingly remove each individual bead?

As in mercury (silver liquid beads)?

 

[bluecheese]

As in the metal beads at the bottom of a thermometer like this. I don't believe they use mercury anymore for thermometers.

A quick search of the threads here found this.

I would say yes to removing the beads. I’m sure they will leech out over time.

Ok. I scooped out the portion of sand that had the beads on it. I think I may have gotten them all. If not, its in God's hands now.

Maybe add some activated carbon as well to combat leaching that may have occured.

Way ahead of you on that one. Thanks.

I believe those are lead or steel balls for ballast. A magnet might work if steel.

Yes, a magnet. Run it over the sand in that spot and it will pull them out.

OMG this happened to me. I went magnet fishing. Took one right off the fridge. It was sort of fun.

Yes, they’ll come out with a magnet. I have a very aggressive cichlid tank with some near 1 footers and they all got going one night and smashed a thermometer…it wasn’t a huge deal - watch your fingers if there are glass shards in the sand you’re digging in though.
