Quick answer
What to know first
- White Biofilm on Driftwood appears as white or translucent slime attached to aquarium driftwood, especially new wood.
- It is usually a temporary biofilm feeding on compounds released from the wood, not algae on plant leaves.
- It is often harmless, though heavy patches can be brushed and siphoned during maintenance.
- Do not use soap or cleaners; gentle removal, time, and grazing from shrimp or snails are usually enough.

How to Identify, Remove, and Prevent White Biofilm on Driftwood
White Biofilm on Driftwood is usually a white or translucent slime on new driftwood. It is a biofilm feeding on organic compounds released from the wood, not algae on plant leaves.
In most aquariums it is temporary and harmless. It can look unpleasant, but it usually fades as the wood finishes releasing easy food for microbes.
How to Remove White Biofilm on Driftwood
Brush or siphon heavy slime from the wood during maintenance. Shrimp and snails may graze on it if they are suitable for the aquarium. Do not use soap, detergents, or household cleaners.
How to Prevent Heavy Wood Biofilm
Pre-soak or rinse new driftwood when possible, remove heavy patches gently, and give the aquarium time to settle instead of repeatedly resetting it.
