Howdy,
I don't recommend it. Is it driftwood, or is it a piece of dead wood that never saw water before? To be suitable for aquarium use, wood should have spent a significant period of time (years) in a flowing body of water or in a swamp. Anything else will have a hard time getting waterlogged and it will also rot, greatly affecting your water quality. Furthermore, conifers are not the best wood for a tank, since they leach more compounds than deciduous trees.
Here's what I do, and how I select my driftwood:
Native driftwood is great - if you know what you're doing.
- the river has to be clean, no industry along the shores!
- the wood has to be well weathered, washed out to the fiber. If it has bark, it's too young. It needs to look like it's spent years and years in the water
- only use wood from flowing bodies of water, never from stagnant areas.
- do not use wood that was covered with mud, it must be located in the stream
- Stay away from conifers. Look at the vegetation along the stream and upstream closely!
Self-harvested wood is a lot of fun. I got my latest piece from a canoeing trip
