Small World Slate & StoneSmall World Slate & Stone Aquarium Gravel - Natural Small Scale Substrate for Aquascaping Planted, Freshwater and Saltwater Tanks - Deep Grey/Black- Size 1/8"-1/4" (6 lbs)
Main highlights- We offer three different sizes of substrate: 1/8" to 1/4" (this listing), 1/4" to 1/2" and less than 1/8" (coarse sand). We love mixing them up for an even more realistic scene Check them out! Perfect for large or small aquariums
- Our substrate is 100% genuine slate stone which is originated, sorted, washed and packaged by our family run business in the USA. It is a beautiful matte dark gray color, with a touch of blue. Because this gravel is natural, some white and brown stones are mixed, which adds to the natural look. Each pack is a mix of small gravel from 1/8" to 1/4". Some pieces may be slightly above or below this range. Absolutely no coating on this stone or any of our stones.
- CLEANING INSTRUCTIONS Even if 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 the water is clear (or almost 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.
- A great gravel for aquariums, saltwater tanks and planted aquariums. The grey/blue colour brings out wood, plants and other inhabitants and decorations. Pairs perfectly with our natural slate stones which come in sizes from 1" to 10" for a cohesive and natural scene. Perfect ladder for miniature models and scenes as well as decorating succulents and other potted plants.
