It is not intended to make the wood sink. • Driftwood that has been confirmed to sink is marked as "Sinking Confirmed". • Even with "Sinking Confirmed" driftwood, it has been dried, so it may take several days for the water to penetrate the wood again and for it to sink. • Although the tannins have been removed, the water may turn brown when used in an aquarium. Please perform tannin removal again if necessary. Thank you for viewing.
