mopani wood?

i let the pieces sit in a bucket for a week doing water changes twice a day
 
Mopani wood is awesome.

If you want to limit the effect on the color of your water, I would suggest boiling for an hour at least once.

As others have said, it's not a big deal if it does change the water color - just preference for you and some fish.
 
i put the pieces in the tank and it looks awsome. the fish already dug out the sand under the big piece. cool tunnel will post pics when i get a chance.
