Prevents substrate, roots, and most bioactive organisms from clogging the false bottom, keeping the drainage layer cleaner and reducing water buildup over time

Separates ABG mix and other substrates from the drainage layer to support proper airflow, water flow, and humidity balance in bioactive terrariums

Made from flexible, lightweight material that is durable and gentle for reptiles, amphibians, and invertebrates such as geckos, frogs, tarantulas, snakes, salamanders, and skinks

Mesh is fine enough to block loose soil and debris while still breathable, allowing effective drainage and preventing stagnant water in the tank

Includes three 18.1" x 18.1" reptile substrate barriers that are easy to cut to size, with extra overlap to wrap edges and stabilize layers in standard 18" x 18" tanks or custom enclosures
