Josh's Frogs Substrate Barrier is a vital layer in all successful naturalistic vivaria. Substrate Barrier fits between the false bottom and ABG Mix layers, and ensures that no ABG Mix falls down into the false bottom, disrupting water flow.
If substrate is allowed into the drainage layer it will fill in the empty spaces where water is supposed to collect, which clogs the layer and reduces its effectiveness. It can even reverse the drainage process by wicking water upwards, back into the substrate above. Oversaturated substrate allows anaerobic bacteria to grow, leading to a smelly and unhealthy environment. When this happens, the only solution is to completely replace the affected substrate. Josh's Frogs Substrate Barrier is a simple, inexpensive, and effective way to prevent this situation from happening.
Each piece of Josh's Frogs Substrate Barrier measures approximately 18 x 24 inches.

The size was great because it can be cut to accommodate the size of the terrarium and can be edited to make room for tubing for the drainage layer. It does an excellent job of separating the substrate from the drainage layer and allows for easy drainage.
This is great size as i will have extra for other builds and help keep soil moist but now soaked since water passes through great product.
The piece was 18x24, so I just folded the excess... my only complaint is that not having 18x18 and having to fold the excess lead to imperfections in my corners.
Does exactly what it says it should. I folded mine to fit my terrarium so it might be too thick for water to run down, so it should probably be cut to size instead. Otherwise a great product.
A simple but essential part for my vivarium. Works well
