BLACK BEAUTY Abrasive Blast Media Fine Abrasive 20/40 Mesh Size for use in Sandblast Cabinet - 25 LBS

I purchased this 4 months ago to use as substrate in my 200 gallon. I was a little concerned with it being glass and my fishes digging in it. However, it doesn't bother/harm the fish at all. I had read on other reviews about it not remaining a dark/solid black so I was prepared for that and still believe it looks and works great (The blue rocks, in the pics, is my fault, their were no blue rocks in my black beauty)!!

I have used this in my blaster primarily to remove rust and prepare metal for finishing for several years now. This is the second container I have bought. Cuts nicely and last long. Ships well the two I have ordered arrived on time and un damaged.

This is a good blast media if you need something agressive for quick rust or paint removal. It's a bit too agressive for aluminum work, I used it to remove rust from carbon steel, and it worked quickly. The box it came in was damaged slightly (probably from the shipping company) but it didn't lose any media. I would guess it to be around a 50-80 grit.

Black Beauty is a very aggressive blasting media. It is great for removing rust and paint from steel and cast iron. It's great for harder materials but use with caution on brass, aluminum or copper! Plastic will be destroyed by it! It is somewhat fine in size but it is very sharp edged and aggressive. It is not expensive in my book and holds up fairly well. When used for a while it can be downgraded for finer work. I have even cleaned painted parts with it at low pressure when it is more pulverized. You should do tests regardless and see how it performs before you use it on something important or valuable...

I used this for aquarium substrate! It's working well and is definitely a more affordable option. Just make sure you rinse WELL before use. It takes A LOT of rinsing!

I used this in my aquarium as substrate, and it’s perfect! Like another review stated, make sure to rinse well before adding into your aquarium! I bought one box for my 60 gallon, I’ll need to purchase another one, but the first bag covered quite well

The media was the right choice for removing old paint and rust from body panels.

I use this to etch glass, steel, and stone and it continues to work great long, long after other media would have broken down and need to be replaced. Have done everything from very thin crystal to gun barrels with no issue, very satisfied.
