Hey DIYers, one of the most beautiful pieces in a natural looking aquarium in my opinion is the driftwood. In the past I've bought all of mine in stores and despite high cost had plenty of problems with releasing tannins into my smaller tanks. I'm ready to experiment using river driftwood along the Bow River in Calgary. I know that conifers such as pine have harsh chemicals like turpentine leach out even with old pieces, so I want to be careful with which ones I pick. I intend to immerse them in boiling water several times before introducing them to the tank.
Here is an example of the wood I've seen on the river bed.
A couple of question with regards to these, is it legal to remove from the river in the city? Is this kind of wood safe for the aquarium? Thoughts? Thanks in advance.
