Description
Practical functions: These crystal rock sands can be applied for the display of your jewelry, necklaces or other ornaments and accessories, so as to stop items from sliding around. If you put them in the fish tank, they could decompose the fish poop and keep it away from flowing in the water. What’s more, they play an important part in water purification. If they are applied to the flowerpots, these help reduce the splashing water when you water the flowers, which are a nice alternative to soil
