Broke Thermometer in Nano
I was cleaning the $2 glass thermometer from my 20 gallon reef since it was covered in coraline and I've been having problems with the suction cup sticking to the glass so after I cleaned it I pressed the suction cup on the glass apparently too hard. I crushed the entire top of the thermometer in the water and very quickly pulled it all out. There are a couple very small pieces of glass on the bottom but when I tried to get them they just got buried in the sand.
Is there anything I should be worried about? There is just air in it right? All the mercury is in the bottom and only the top was affected.
I'm going to get one of those digital thermometers tomorrow.
