I've had some Mopani driftwood sitting in a bucket for 24 hours and there's no sign of discoloration in the water. Is it ready to go in the aquarium? Do I need to boil it?
I would suggest not boiling it on personal experience! When it gets boiled it tends to get this nasty slime stuff on it! If you are ok with putting it in tank then go for it. It may leach the tannins in the tank, but it isn't dangerous to the fish just annoying to you. The fish actually prefer the tannins so you are good to go!
