If placing in a tank, you may need to perform submersion work yourself. • Although the above processing has been done, it has not been confirmed that all tannins (wood resin and pigments) have been removed. • There is a possibility that brown pigments (tannins) will leach out when submerged in water. This will not affect the animals, but if you are concerned about the water color, please perform additional tannin removal. If you have any questions, please feel free to contact us.
