Question 3M Color Quartz Crystal "T" Grade Black Sand

I just re-did my substrate with Turface and 3M Color Quartz Crystal "T" Grade Black Sand. I was wondering if anyone who has used the 3M Color Quartz Crystal "T" Grade Sand....Did you have an oily-looking blackish slick when rinsing this product? I wasn't expecting this when I used "Rex's method of rinsing substrate". (BTW, his method made it so much more easier to rinsing substrate! Thank you Rex!!) I was just expecting dusty particles like when I rinsed the Turface. The 3M sand left quite a black oily film in my bucket and on my hands. Once in my tank, things were fine. I'm just hoping this 'oily stuff' doesn't harm my plants and inhabitants.

I never had an oil slick from the 3M stuff. I did get a bit of the very fine dust on the water surface during the first rinse. Second rinse it was all clear. I didn't bother rinsing for one tank I set up, I had no problems with it.


Aquascape? I'm a crypt farmer.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

i rinsed my colorquartz in a pillow case in the bathtub, and i thought my wife was going to KILL me. it left a black residue all over the tub (but it came off easily with some soft scrub and a scrubbing sponge). once the water ran clear, I placed the sand in the tank, did a couple of fills and water changes with a delicate flow of water into the tank to get the suspended "fog" out of the water, and haven't had any problems at all. fish have all been healthy, and plants grow fine. it is worth noting that i've got mine mixed with onyx sand.
