Fluval Natural Mopani Driftwood, Large

• Won't float
• Releases tannins (brown color) into the water which is great for fish and shrimp
• Boil or soak the wood to get less color in your water
• A "fluffy" biofilm will appear on the wood when underwater, this can be physically removed with a scrub or left for fish to eat, will go away on its own
• Creates a natural and authentic effect.
• Cleaned and ready for use
