Description

Spiderwood is prized for its fine, twisting branch structure – it looks like tree roots at aquarium scale, which is exactly why it is used for tree-style and forest scapes. The rough bark surface also gives moss and anubias something to grip.

Pieces are natural, so each one differs. We select for good branching and send a photo of the actual piece before dispatch if you ask.

Preparation

• New spiderwood floats. Boil it or weigh it down for one to two weeks until it waterlogs.
• Expect a white biofilm bloom in the first few weeks. It is harmless, temporary, and shrimp and otocinclus eat it.
• It releases tannins that tint the water amber. Boil it and use activated carbon if you want clear water, or leave it for a blackwater look.
• Boiling also sterilises the wood, which is worth doing regardless.
