Instructions
Sinking Driftwood With Slate
Lay a thin line of silicone along the bottom of each piece of driftwood.
Attach a piece of slate to each line of silicone, pressing firmly to secure it in place. Wait for the silicone to dry.
Drop the driftwood gently into the aquarium, slate-side down. The driftwood will sink to the bottom.
Submerging Driftwood with Fishing Line
Tie a length of fishing line to a piece of driftwood.
Tie the other end of the line to an aquarium plant.
Embed the aquarium plant in the tank's substrate. The submerged piece of driftwood will eventually sink to the bottom.
Weighting Driftwood with Lead
Drill three small holes in the bottom of a piece of driftwood.
Fill each hole with molten lead.
Seal the holes with silicone.
Drop the driftwood piece gently into the aquarium, lead-side down. It will sink to the bottom.
