Zoo Med Eco Earth Coconut Fiber Substrate Brick — Fine Coir, Expands to 7–8 Liters

The fine one. This is the stringy coconut fiber (coir) that comes compressed in a brick and blooms into 7–8 liters of soft, soil-like substrate with just water.

• Fine, stringy texture: gentle on bellies and perfect for burrowers, frogs and geckos
• Humidity hero: absorbs and slowly releases moisture — the base layer of tropical and bioactive setups
• One brick, one enclosure: the right size for a single terrarium or a substrate refresh
• Trusted name: genuine Zoo Med Eco Earth, the brick keepers have used for decades

How to use: place the brick in a bucket, add warm water, let it expand, break it up by hand and spread. Mix it under chunky husk chips for a layered, natural floor.

Start with one brick — or stock up and save with the multi-packs. That's the ShopperBear way.
