Tannins from Mopani wood
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?
