LOL,
Ok, dont wash your sand, hopefully all works out fine.
FWIW, In the past few years ive cured both sand and rock for various purposes,and the latter in thousands of pounds.
In the rock and sand batches i have found contaminants that would scare you into washing your sand and inspecting your rock.
I have ran a magnet thru various batches of sand and found...wouldnt ya guess ?...large metal shavings..hmm,just the kind that you would find from an excavator of sorts....and guess what ? it all had fancy aqaurium packaging.
In rock i have found aluminum cans and bottle caps imbeded in the rock that would have had to have been there for many years....i still have the coralline encrusted pieces of some(the ones that i could remove from the strainer in my pump :shock: )
I wasnt speaking from my arse.
It doesnt mean anyone in paticular is guilty.... they all are!
It just means do what you can to keep it out of your tank.
Again,Choose as you see fit.
