I have in my possession a 5 gallon bucket full of large pieces of glass from an old PPG plant, they do have lead in the glass, and more than likely contain a small amount of arsenic (a lot of glass does) but what I'm wondering is if I can safely put these pieces of glass in my aquarium (after making all the edges smooth, so as not to cut anyone in there) without damaging any of the fish or turtles?
