Hello everyone, I have a 12x12x18 Crested Gecko terrarium with Eco Earth as the substrate. I purchased the three pack of bricks, and followed the instructions on the packaging. It seemed like a lot of water to add to it, but it soaked it up and expanded fairly quickly. I added it to the terrarium approximately 30-45 minutes after I added the water. As the title of the thread suggests, the Eco Earth is molding with a white looking mold. Should I have let the Eco Earth dry before I put it in the terrarium? Or would it be easier to buy the loose stuff?
