|treetom||Coal slag is the left over material of coal being burnt in power plants. I used to unload coal trains and seen hills of the stuff. They sell it for other things as well like for ash trays, putting down on snow and ice, as well as blast media. The chances of getting metal in your bag is good because most coal burning power plants burn a small (compared to the amount of coal burnt) percentage of shredded tires. And tires contain wire and would then possibly not be consumed in the burning process. Also sand or stone fragments would contain silica which would turn to glass given the high heat that the coal is burnt at. Actually, a lot of elements and compounds could fuse to form glass like material given the extreme temps they would be subjected to.|

^^^ That looks real good! At worst you will end up with a natural "dirt" look if they ever get totally mixed up.
To those other posters concerned about the "shards". I had a few of those I noticed in my 3 bags of the stuff. When I spotted them I pulled a couple out...no ill effects to any of my fish.
Couple of mine were indeed metal shavings of some sort...who knows. After all folks, it's an industrial by-product commonly blasted out of a gun to remove paint off cars, lol. My point being that it probably hasn't been inspected for purity at the level of something that was intended to go in an aquarium. So, as with any DIY project...a bit of self inspection and an acceptance of slight imperfection should probably be the norm. You might wanna sift it, you might wanna rinse it, it might take a bit of work. Good news is you just saved $100 on black sand.
All kidding aside my corys are fine, my shrimp are fine too, and even my "special" oto that thinks it's a cory is fine. (He tries the whole sucky sucky thing on the black diamond substrate. Very funny.)

As requested: I don't know how this will ultimately homogenize out (in terms of black:tan ratio) But it looks good to my eye. And I had to shoot these with a flash, so the color may be a titch off. In a 72 gallon bow, each 50lbs bag => 1" of substrate thickness (aprox).

In my 72 bow front I have 2 bags of tan pool sand and 1 bag fine coal slag for a total of 150lbs of fine substrate. I like the results . . .

|djscotty||I just did a couple of thorough washes and then transferred to the tank. I then had a old HOB filter that I used for a couple of days and all of the oil disappeared and haven't had any other problems.|
