Root-Polished 20-30cm
Many woods are buoyant and may need to be soaked to become waterlogged and sink. Woods may require temporary weighting with rocks, anchors, or other heavy objects to prevent floating until they absorb enough water to fully submerge.
Woods may release tannins during initial setup. These tannins give the water a cognac-like color, similar to natural river systems. This is a natural process and not harmful to aquarium life. Tannin levels can be managed through regular water changes or by using Seachem Purigen in the filter.
To minimize tannin release at the start, you can boil the wood in water for several hours before use, or soak it and perform frequent water changes.

Can I use this wood in a freshwater aquarium?
Yes, this root-polished wood is suitable for freshwater aquariums and can be used to create natural-looking environments.
Will the wood release tannins when placed in the aquarium?
Yes, the wood may release tannins during the initial setup, which can give the water a light brown or cognac color. This is natural and safe for aquatic life.
Do I need to soak the wood before placing it in the aquarium?
Yes, it is recommended to soak the wood in water for several days to allow it to absorb water and sink properly.

The wood looks very natural and adds a realistic touch to my aquarium. It sank after a few days of soaking and the water turned slightly brown, which I like because it mimics a natural river. I did a few water changes and it stabilized well.
Blake Allan –
It arrived in good condition and fits well in my tank. I used rocks to keep it from floating initially. After a week, it sank completely. The tannin color is subtle and not overwhelming.
Katherine White –
I boiled the wood for 3 hours before use to reduce tannin release. It worked well and the water stayed clearer during the first few weeks. Great for creating a natural forest background.
