well I have had a few PMs on here and 3reef from people who have used this sand in their tanks for years with no problems.. so I'm kind of on the fence ATM..
I would like to see conclusive evidence that its either bad or good, it is magnetic, but not all of it. so the only issue I see so far is I cant use a magnetic cleaner. but obviously if its a harmful metal it could pose other problems in the future. this is why I am skeptical, as people say its fine and some say get it out.
