Black Diamond

[amberoze]

I'm wanting to use black diamond blasting sand as a cap for organic garden soil in my 16 gallon bowfront. I was wondering if the is a specific grit size I need to get (xsmall, small, medium, large, xlarge are the choices), and if I should rinse it first.

20-40 grit, and you should rinse it.

Yes, you should rinse it very thoroughly. I run a hose in a bucket and rinse with castille soap. I believe I used 20-40 as well.

I used 20-40 and rinse it like crazy. I have found some slight color difference from bag to bag as well.

Thanks for the replies. Unfortunately, the only store near me that carries it, only carries 30/50 (fine grit), and I already bought a bag. I'll of course be rinsing it based on the recommendations here, I just hope that it doesn't rinse into nothing because of the finer grit.

I found Black Diamond requiring less rinsing than other sands/substrates I've used in the past. It may slightly cloud your tank after a brief rinsing, but it should clear up within hours or overnight.

Here's a question. Can I rinse this stuff in my bathtub? Cause it's cold outside, and that makes it near impossible to do things with water without freezing my hand off.

Sure, if it's clean why not?

Warning though - this stuff will clog your drains so tight it'll take a snake to clear it, so don't let more than a few grains down there!

I just used a big salad bowl to rinse 150 lbs of mine in the kitchen sink. It didn't take all that long, and you can just point the water stream right into it and let the water overflow the bowl and all the crud spills over the side with it. Move it around (if I had a sprayer I would use that) a bit and next....

I found it very clean as well. The rinsing does not take too long.

Does it come in in a bigger size grain than 20-40?

No.
