Bones for substrate and decor? Antler? Bamboo?
Anyone know a good reason not to use old, weathered bone for plant attachment and decor in a hard water tank? Assuming the proteinaceous stuff is largely rotted and leached out of it and the tank is very thoroughly cycled with the bone in order to process any remaining nitrogen-containing material?
Has anyone here used deer antler? I see where people have done it but I don't see follow-up to check whether it was okay over the very long run.
What about bamboo? I have a small, partially crushed basket woven out of thin strips of bamboo that I think would look interesting partially buried in the substrate. Great texture for plant attachment and for tiny fish or shrimp to explore. It will eventually rot but that's okay.
