burr740 Rinse it well and dont sweat the oddball particle here and there.

It's great. Cories love it.

Lonestarbandit I used it before no issues. Use playsand now and no issues there either.

Kubla Loads of people using this in their tanks for a while. I've got it in one tank, love it, and have no issues with it. Are there real problems reported with actual use, or is it all just non users complaining that it looks like their could be problems with it.

Our local Harbor Freight carries it. It's not listed on the web site, but it must be in their system somewhere.

Absntmind I purchased a couple bags of this from our local TS with the intent of changing my substrate from play sand. While rinsing I noticed a LOT of the needle like glass pieces of all sizes, some very small. After rinsing for almost an hour and realized I would never get most of it out I decided not to go with it. I researched and read many people use it without issue, though if I'm going to put media in the tank to be used for a length of time (years?) I came to the conclusion that it'd be better to just wait and spend the extra money for something else.

I love the way it looks but seeing as some fish take the substrate into their mouths, even passing it through the gills, I couldn't use it in good conscience. Yet I also understand the quality of this stuff varies from area to area.

Just my .02

I have this stuff in my tank and my horse faced loach sifts it through his gills constantly with no adverse effect.

chomper149 question regarding the 1st set of pictures, just looking at the first set of pictures you can clearly see a few coal slag rods? that could potentially be spikes? whats everyones opinions on those? are they in every bag and no one has had a problem with them sticking in fish gills or the like?

Nonsense. People.. if you haven't got 1st hand experience with this stuff please refrain from FUD. This stuff is silky, not abrasive in any way. Yes it is BLASTING MEDIA but if you know anything about sandblasting you know that this stuff is on the bottom of the aggressive scale for it's purpose. No catfish is going to suffer from it. No iron is going to turn your hands black. There no no OIL in it. It is thoroughly washed before it's bagged. Some particles will tend to float when you put it into water but will settle quickly. If you read the NUMEROUS threads on here you will see that it's an inert sub with no CEC value that is suitable for just about any scape.

It is also NOT the same as Black Beauty. That is a different brand, and not to be confused.

People on the west coast have trouble getting it. You might want to call ATI (1-800-343-0117) and register your thoughts with them.

clayman65 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.

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