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.

I wasn't referring to the black sand but rather the black substrate which is larger granules, looks awesome!

If your worried about iron in your tanks, the one pet store I worked at had no less then a dozen rusting razor blades in their system when I finally cleaned out the entire thing. I doubt they had any effect on the tanks. When I removed them everything was the same.
