Updated: Feb 20, 2021

Driftwood is more than just an added decoration to your aquarium. There are many great reasons to add it to your aquascape. Driftwood can be harvested from any body of water or the shore line.

Instead look for broken off branches or dead and dried out trees to harvest from.

When collecting driftwood from a body of water or the shoreline, or other dry land sources it is critical to clean and sanitize it before adding into your setup. First you soak in hot water and scrub with a stiff bristled nylon brush. After scrubbing rinse off using a hose with pressure nozzle. After this you will soak it in a weak bleach solution for 24-48 hours. After bleaching you must rinse throughly, small pieces can be boiled to rinse and sanitize. Rinse until there is no remaining chlorine scent. Before adding to your aquarium soak in a de-chlorinator such as prime for 48 hours doing a water change and adding more prime at the 24 hour mark. Or alternately you can leave the wood outside to dry for 2-4 days. Wood can then be secured to a piece of slate or other aquarium safe rock and placed in your tank. Another option is to cure the wood. Fully submerge wood in water and let soak for 1-2 weeks. As tannins leach out and darken the water or every 2-3 days continue to do water changes and rinse off the wood before refilling. Some pieces of wood may take longer to sink and/or be free of tannins.
