LECA (Lightweight Expanded Clay Aggregate)
LECA (lightweight expanded clay aggregate) is a great filler material for the drainage trough of Amazonia vivariums. It takes approx. 1 Litre of LECA to fill the trough to the correct level. One order is 1 litre.
LECA is nearly half the density of calcined clay and about the same density as horticultural charcoal, so it's an ideal substrate option for filling the trough if you don't want to culture springtails or other feeder insects. We recommend covering LECA with a material such as horticultural fabric or synthetic screening to prevent smaller-grained substrate materials from filtering down into it.
Please note this is a pre-order and will start to ship in June 2020. Please see our Pre-order FAQ page for more information.
