i rinsed some used sand a month or 2 ago and then left it in a trash can that's only ever been used for reef stuff. The can had a lid on it but was vented via 1/2" PVC that used to be an overflow. I went to use the sand today and noticed there was still water laying on the top so in an attempt to dump what water I could some sand came crashing down and I lost a handful. This unleashed a god awful smell and the sand from underneath appears dark. Is this mold? Is the sand garbage? What do you folks think? I don't want to buy sand
