If you put it in a tank, you may need to perform the submersion process yourself. • Although the above treatments have been performed, we have not confirmed that the tannins (wood resin and pigments) have been completely removed. • There is a possibility that brown pigments (tannins) will be released when immersed 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.
