WIO Silver Shadow Gravel Mix 2kg

WIO Silver Shadow Gravel Mix is slate-like substrate which is great for worn riverbed scenes. This turns a lovely dark grey colour when wet, making green leaved plants stand out really well when placed together. It is inert so it will not affect the pH level making it suitable for use in both soft and hardwater set ups. Particle sizes 1-40mm. Available in 2kg packs.
