| Category | Pebbles And Pea Gravel For Water Filters |
Product Description: These brown pebbles and pea gravel, sized between 6-12 mm, are ideal for water filtration systems. With their natural oval shape, they effectively filter water while adding a decorative touch. Gravel, which consists of loose rock fragments, forms naturally through sedimentary and erosive processes or is commercially produced as crushed stone. Pebbles, ranging from 4-64 mm in size according to the Udden-Wentworth scale, are larger than granules (2-4 mm) and smaller than cobbles (64-256 mm). Rocks composed primarily of pebbles are known as conglomerates.
