SPIDERWOOD XL

Golden-brown azalea root for the aquarium, about 50 to 60 centimetres.

This is the largest of the range and meant for a tank a metre across at the least.

Measure the tank before ordering. Sixty centimetres is more in length than many expect, and branching wood takes width and height as well – the limbs may reach far from the trunk.

A large piece is best set in the tank before the plants go in. Moving the wood afterwards tears the planting loose and stirs the substrate.

Soak the wood at least four days so that it sinks.
