Thanks for that. Can you suggest the proper one I can buy in smaller quantities in Northern California? I only have a few 20 G tanks and can't handle 50 pounds!It depends on what the dark sand is made from. Natural black sand, composed of grains of basalt, are fine. Black sand composed of crushed coal slag is glass with sharp edges and can contain toxic residual chemicals; not fine. Also note that dark sand tends to make apistos show duller colors than neutral color sands.
