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