If you put it in a water tank, you may need to perform the submersion work yourself. • Although the above processing has been done, we have not confirmed whether the tannins (tree sap and pigments) have been completely removed. • There is a possibility that brown pigments (tannins) will come out when soaked in water. It will not affect the organisms, but if you are concerned about the color of the water, please perform additional tannin removal. If you have any questions, please feel free to contact us.
