I have black sand and love it man. I used to have white sand but since I have changed it I would never go back to white. The black makes all my corals stand out! When u pick it out though make sure u get the non-magnetic type of black sand! And my favorite part about it is when your sand needs to be cleaned you can actually see it bc about a cm down it makes a layer of all the stuff u can see, clean, and see when it gone! Also get thicker sand not too fine! That'll make it very easy to clean and keep clean!
