metal particles in live sand!...should i worry or not!?

[danielcassar]

Hi all,my friend gave me his live sand since he stopped with the hobby....and coincidently i found that in the live sand there are very tinny metal particles! these were found cause my glass cleaner magnet fell in the bucket and when i picked it there were tiny black particles with it!.....should i remove the sand that i already put in the refugium?

thanks

Probably it is magnetite, a naturally occuring component of many beach sands. I guess I wouldn't worry...
