So I was sifting threw the sand I am about to use on a new 75 gallon reef and I found a penny.  I know copper is completely toxic to inverts so I was wondering if you guys think the sand would still be safe to use in the reef?  I am almost positive the penny got in there when the sand was dry and in a bucket, AFTER I drained my last reef.
PLEASE HELP!!!
Thanks
