Aquarium white and black mixed gravel 1Kg

Aquarium white and black mixed gravel in the 4–6mm grain size is a highly popular, modern substrate option that offers a striking visual contrast while supporting a healthy tank environment. At 4–6mm, this coarse gravel provides excellent water circulation around live plant roots, preventing toxic anaerobic gas pockets from forming. It is also much easier to clean with a standard gravel vacuum compared to fine sand.
