Our Driftwood is not processed to be safe for any animal tanks. Please use our custom services to have the piece you love boiled, to help prepare it for animal use. We do not use chemicals or cleaners on our driftwood. It is found and washed off with water only. When selecting to have Natural Driftwood Art boil your piece please allow 2 weeks for the item to ship. It must be allowed to dry thoroughly before shipping or additional shipping costs will be added to your invoice.
