Materials Substrate is a mix of fine sand/gravel mixed with some red clay soil collected from local streams in Victoria, Australia.

Rocks and driftwood were also collected from rivers in the region. The wood is presumed to be a species of Eucalyptus.
Additional Information The Snag is a representation of woody debris habitats in a lowland stream in south-eastern Australia. All of the plants and livestock in the tank are indigenous to the region with the exception of Ludwigia palustrus, an introduced species now considered "naturalised".

This tank is not heated and CO2 is not used.

Lighting varies seasonlly with day length (8 hours in winter and 10 hours in Summer). The on/off times of the two light fittings are staggered by 30 minutes to provide a brief sunrise/sunset effect.

Fertilisation is through daily additon of small quatities of home-brew trace and macro nutrients.
