ProRep Bio Life Leaf Litter Brick

The ProRep Leaf Litter Brick is a compressed block of broken leaf litter designed to help build the layered structure of a bioactive vivarium or terrarium. Available in two sizes to suit enclosures of different scale, it expands on hydration to recreate the natural forest floor carpet found in tropical and woodland habitats.

Why Leaf Litter Matters in Bioactive Setups

Fallen leaf litter is far more than decoration. On a natural forest floor, it forms a dense microhabitat that shelters insects, amphibians, and small reptiles — offering cover from both predators and temperature extremes. Replicating this layer in a vivarium gives your animals the same functional refuge and behavioural opportunities they would have in the wild.

Supporting Your Clean-Up Crew

Leaf litter is the foundation that sustains detritivores — the woodlice, millipedes, and springtails that keep a bioactive enclosure functioning. As the leaf matter breaks down, it enriches the substrate with nutrients that support both the clean-up crew and any live planting in the enclosure. Without it, even a well-established bioactive setup loses a critical layer of biodiversity.

How to Use It

The brick format makes storage and deployment straightforward. Hydrate the brick to expand the compressed litter, then layer it over your existing soil-based substrate. For best results, combine it with larger whole leaf litter to build up the varied textures and depths typical of a forest habitat. This layered approach more closely mirrors the interconnected ecosystems these animals come from.

Choose the size that matches your enclosure and how frequently you refresh or top up the litter layer — both options are listed above. Keeping a spare on hand means your bioactive build is never interrupted.
