Maintain a clean and efficient drainage layer with this reptile terrarium barrier. It keeps loose substrate out of the false bottom while allowing proper water flow.

Lightweight and easy to trim, it's perfect for bioactive enclosures housing geckos, frogs, mantises, and more. Includes two 36" x 18" reptile substrate barriers for versatile setups.

  • Works as advertised
Used in two terrarium projects and does a good job at preventing the soil from seeping down into the drainage layer. You can see in the attached photo the gravel is separated from the soil just fine

  • Buy it , worth the money.
Fits perfectly for a bio tank can be cut or use both sheets to fit any tank up to about a 50 gallon. So easy to use, of great quality and durability. If putting in a bio tank there is no cleaning involved. Definitely worth the money considering you get two sheets in each pack.
