• Sold by the box, not cherry-picked — 15 kg of 45-60 cm pieces, enough to build a full layout rather than accent one corner of a tank.
• Genuine hardwood driftwood — dense wood that eventually sinks and holds its shape, unlike lightweight softwoods that break down over a season or two.
• Releases tannins — expect the water to tint amber to tea-coloured for the first weeks to months in a new setup. This fades naturally with water changes, or faster with activated carbon.
• Every piece is unique — shape, branching and colour vary between pieces and between boxes. The photo is representative of the wood type, not the exact pieces you will receive.

Bioscape does not publish an exact piece count per box — with natural branch and root sections in a range of shapes, the number of pieces that make up 15 kg at 45-60 cm each varies box to box.

Amazon wood is dense and generally sinks once fully waterlogged, but a piece straight out of the box will usually float for anywhere from a few days to several weeks first. Submerge it completely in a bucket or tub, weighed down with a clean rock or held against the glass with a suction mount, until it stops trying to surface — this can take one to several weeks depending on the piece. Smaller offcuts can be boiled to speed up waterlogging and take the first, heaviest flush of tannins out before the piece goes in the display tank; boxes at this size are generally soaked rather than boiled, given how large the individual pieces are.

Tannins soften water slightly and nudge pH down, which suits soft-water species such as many tetras and Amazonian cichlids and is part of the aquascaping look this wood is chosen for. In a hard or heavily buffered tank the pH effect is negligible. If you want clearer water rather than the tannin-stained look, run activated carbon such as Bioscape Premium Carbon Pouches until the tint settles, and expect to repeat it periodically as fresh tannins continue to leach out over the following months.

Suitable for:

• Freshwater aquascapes and cichlid biotopes built around branching driftwood structure
• Soft-water planted tanks where tannin staining and a lower pH are welcome
• Mounting moss, ferns and epiphytic plants along the branches

Not suitable for:

• Marine or reef tanks — this is a freshwater driftwood product
• Anyone who wants to avoid tannin staining without running carbon
• Buyers who want a single accent piece rather than a full 15 kg box

• Bioscape Premium Carbon Pouches — for controlling tannin staining once the wood is in the tank.
• Seachem Flourish Glue — for anchoring moss and epiphytic plants to the wood.
• Bioscape Amber/Gold Spider Roots Medium 20-30cm — a finer, branching wood type to layer against the heavier Amazon wood pieces.

This is a natural product with no manufacturing warranty, though your rights under the Australian Consumer Law still apply to quality and fitness for purpose. At 15 kg this box is heavier than most decor items — check the freight estimate at checkout, as cost and delivery method may differ from a standard small parcel.

Will it float when I first put it in the tank?

Most likely, at first. Amazon wood is dense but still needs to fully waterlog before it reliably sinks, which can take one to several weeks. Soak and weigh it down in a separate container until it stays under water on its own, rather than fighting it in the display tank.

Do I need to boil it?

Not necessarily at this size. Boiling speeds up waterlogging and strips out the first, heaviest tannin flush, but pieces this large are more commonly soaked over a longer period instead, given the pot size boiling would need.

Will it turn my water brown?

Yes, at least for the first weeks to months. This is normal tannin release, not a sign of a problem. It fades with routine water changes, or you can speed it up by running activated carbon.

How many pieces come in the box?

Bioscape doesn't publish an exact count. Pieces are natural branch and root sections in varying shapes, so the number that adds up to 15 kg at 45-60 cm each varies from box to box.

Is it reef or marine safe?

No. This is a freshwater driftwood product, sourced and sold for planted and aquascaped freshwater tanks.
