I'm the friend Fliger mentioned who has had the black sand for a year. It does show the detritus but I really don't mind because it tells me where I need to clean and where my dead spots are. If you let it go and don't keep up then it might start to look unsightly. I think it handles flow a little better. No sand storms just a few rolling canyons.
I absolutely love the way the colors pop at you. To match I also have the back panel black acrylic.
