Soaking Driftwood - Green Tannins?
So I got this nice piece of malaysian driftwood from a reputable LFS and started soaking it in a bucket in an attempt to get as much of the tannins out as possible before putting it in a tank.
For the first week or so, the bucket water would be yellow and eventually turn brown if I didn't change the water for a while - totally normal.
Then to speed up the process, I boiled the driftwood for 15 mins and then the following day for about 2 hrs.
Now w/ the driftwood left in the bucket to soak, the water takes on a greenish hue, not yellow. Any ideas why this is and should I be concerned?
Thanks in advance!
