Black Diamond 20/40 Closeup
 

Tractor Supply got a new shipment of Black Diamond blasting abrasive, yesterday, so I bought 100 pounds. This is a closeup of what it looks like...

I can't find that stuff around me.

It's supposed to be the same thing as Black Beauty... if you can find that.

I googled around and found a company called United Western Supply, in Seattle that might cary something like it. Maybe give them a call. They list it as one of their products, on their website.

I have looked and looked and the only one carrying this is Tractor Supply, Co., unfortunately the closest one to me is about a 2 1/2 hour drive one way.

Ageless, still I am.

this stuff is great (and cheap), but make sure to thoroughly rinse it or you could end up with an oil slick on your tank!

Is it just me, or does it appear to be too abrasive? I'd be concerned with my corys with that stuff in there. It does look amazing though

it's not so bad, i've run my hands through it for hours cleaning it and came out fine... cory barbels usually disintegrate due to water quality, not "sharp substrate" which is more of a myth than anything. i've heard a good number of success stories (and no failures) with black diamond and cories- search "black diamond cories" on the forum or just google if you don't believe me.

I believe you, but I know all about cory barbels disintegrating from water quality. I was referring to their bellies really. :O

I'm looking at it @15 megapixels, and I can't see any sharp edges... nothing even close to glass. There are sharp angles, but everything is rounded. I'm more worried about what looks like metal flakes everywhere. It's almost like Edward fell into a batch and got chewed up in the machine... hopefully.

my 6 peppered cories are fine

I keep a raphael, dragon gobies, cory cats and many more bottom dwellers over blasting grit. Mine is a finer grade. In most of my tanks, it is mixed with natural gravel or eco-complete for a bit more natural churned up kinda look.

There is metal of some sort in black diamond. If you run a magnet up and down the bag you will hear tiny grains following it...... is it harmful to our fish ? Who knows !

I use this, very cheap, a bit weird when washing it, but totally safe. Bottom dwellers fine with it, mbuna moved mouthfuls of it, all good. Plants grow in it, too.

It is sand blasting grit/sand.

Maybe that's the Iron they refer to, when they describe it's contents.

I just put black diamond in my tank. It's definitely not sharp since I was mixing it around with my hands rinsing it. The weird thing about it is the wire pieces in it. Some look like small pieces of steel wire and others look like small glass tubes.
