hey, that media report appears to have been done on used media. i don't think that's a report on new product.
the diamond pro looks just like it and should be fine. particle size should be 2-5 mm like regular agricultural perlite.
also, there is nothing wrong with diatomaceous earth or DE from napa auto parts. i think that # was 8855. a completely different substance than turface, produced another way, with almost identical physical properties.
napa 8822.. and not all napa store cary their own brand of floor-dri (8822). I'm using it with the rice hulls. Works great but wish I could locate turface locally and give 'it' a go. I saw your link d9, none really local for me.
