Metal ball bearings from thermometer....dangerous?

[Rippin]

Hi all,

Wondering if any of you have experienced this....
My thermometer broke and a small amount of the metal ball bearings that weighs down the unit was scattered in the nano tank before I had a chance to take out the thermometer.

Do you think these metal ball bearings will cause water quality problems further down the road?

Trying to find all of them to take them out would be a bit of a pain...
