Bogwood contains tannins (organic material) that will leach into your water giving it a tea coloured and stained colouration. This is perfectly harmless. In fact some aquarists even find it desirable when trying to recreate Amazonian black water conditions etc.

- Why does my tea kettle have black residue? This residue, called scale, is a harmless buildup of minerals -- primarily calcium and magnesium, found in hard water. To remove the deposits inside your tea kettle, boil equal parts white vinegar and water. Turn off the heat, and let the kettle sit for a few hours.
- How do you remove tannin from driftwood? Just like steeping a tea bag in hot water, boiling driftwood in a large stockpot encourages more tannins to leach out faster, thereby shortening the curing process. More importantly, boiling sterilizes the driftwood, killing algal or fungal spores that can take hold once introduced into the aquarium with the driftwood.
- How is black lacquer made? Raw lacquer can be "coloured" by the addition of small amounts of iron oxides, giving red or black depending on the oxide. There is some evidence that its use is even older than 8,000 years from archaeological digs in Japan and China. Later, pigments were added to make colours.
- How long does it take to get tannins out of Mopani wood? Like any wood, Mopani will impart some tannins into the water after it's submerged, so if you're not into "the tint", you probably want to soak it in freshwater for a week or two to "crack off" some of the initial burst of tannins and other organics contained in the wood structure.
- What does harmless black mold look like? When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it. Most of the time, black mold has a slightly furry appearance.
- Can I put bogwood in my aquarium? Bogwood can be made up of wood species from all over the world, but select bogwood from aquatic stores to make sure its safe to be submerged with fish. Place it in the tank and it should sink, but some may float for several days before sinking.
