Aquarium Substrate | Grey - Coarse Sand

Our coarse sand substrate is 100% real slate stone that is sourced, sorted, washed and packaged in the USA by our family-owned business.  Each bag or box is a mix of coarse sand sized from 1/32" to 1/8" (some pieces may be slightly above or below this range).  Absolutely no coatings on this or any of our stones.  An excellent gravel for aquascaping aquariums or use it as a topper for soil in a planted tank.  The grey/blue color makes wood, plants, and other inhabitants  and decorations pop. Pairs perfectly with our larger slate stones that come in sizes from 1 inch up to 10 inches for a cohesive, natural scene. This coarse sand substrate is a beautiful, deep grey matte color, with a hint of blue.  Because this is a natural stone, some white quartz or brown stones may be mixed in that add to the natural look.   Due to shipping and handling, this gravel will arrive quite dusty.  This is normal for this type of stone.  Be sure to wash this gravel repeatedly, in water ONLY, u
