Question Tannins from Mopani wood

Hi All,

I pick up a chunk of mopani last night at my LFS and have been boiling it, trying to get most of the tannins out before putting it in the tank.

It's been in the pot for 5 hours now (with hourly water changes, and an overnight soak in the middle) and it still turns the water dark brown. How long am I going to have to do this for?

If it's anything like boiling acorns... two days.

And, yes, acorns are edible if you boil the tannins out then mush them to acorn flour and make bread out of it. yum!

I didn't boil my driftwood, I soaked it and changed the water for a week... But then I got mine from the shore near here. I don't even know what kind of wood it is. It was just a pretty piece of driftwood. Fish seem to like it though.

I boiled a piece of Mopani wood 2-3 times a night for almost 2 weeks. When I went to bed I would put it in another batch of clean hot water and let it soak. Mopani wood has ridiculous amounts of tannins but it's worth it when you get it done. I think it's one of the nicest driftwoods you can get. It will never boil absolutely clear but the water will get much lighter. At that point I put it in my tank and it never leached any tannins into my tank. The boiling water forces out stuff that won't normally come out in your tank.

Boiled all of mine for only about 45 minutes changing the water once. I never got to the point where the water was clear, but never had any problems with tannins leaching into the tank afterwards.
