Our substrate is 100% real slate stone that is sourced, sorted, washed and packaged in the USA by our family owned business. It is a beautiful, deep grey matte color, with a hint of blue. Because this gravel is natural, some white and brown stones are mixed in which add to the natural look. Each box is a mix of gravel from 1/4″ to 1/2″ (some stones may be slightly above or below this range). Absolutely no coatings on this or any of our stones.
An excellent gravel for aquascaping aquariums, saltwater tanks and planted tanks. The grey/blue color makes wood, plants and other inhabitants and decorations pop. Pairs perfectly with our Natural Slate Stones that come in sizes from 1 inch up to 10 inches for a cohesive, natural scene. Perfect scale for miniature models and scenes as well as a topper for succulents and other potted plants.
CLEANING INSTRUCTIONS – Even though it has been washed, this substrate will arrive quite dusty due to shipping and handling. This is normal for this stone. Be sure to wash this gravel repeatedly, in water ONLY, until water is clear (or mostly clear). It is common for dust to float on the surface during rinsing and filling. Place cleaned gravel in your empty tank (no water), and decorate the tank before adding water.
