Has any one had any experience with Mopani driftwood? Any suggestions to give me other than what I have already tried? I bought 2 pretty nice pieces the other day at the lfs and I am trying to get as much of the tannis out as I can but it seems endless. I have about 12 hours of hard boiling into it so far and when it is not boiling it is soaking in water. After I leave it boil for about a hour and change the water it is still a dark coffee color.:help:
