Used sand smells putrid

[WhiskeyCoffee]

So I picked up a used 75g and the guy threw in his Caribsea sand which I wasn't sure if I was going to use or not. Well tonight I cracked open the bucket he gave me, and the sand had a nice sand/beige color to it. I mixed it up and almost vomited due to the extreme sulfur smell. I noticed that the sand under the top layer had a grey color. I rinsed it multiple times and it still just looks grey, almost like wet cat litter. I'm guessing I should just trash this stuff?

I would trash it. New sand would be an easy, cheap way to avoid alot of headache down the road.

Or bleach, rinse and dry in the sun.

IMO it's not worth saving......go with a bare bottom tank and save the money for something else and save the bother for another occasion. Or just buy new sand....doesn't cost much.
