Title: Traps mildew and mold- hard to clean!
Review: The inside of this tank has so many cracks and crevices that mildew and mold collect in spots that are impossible to clean, even with wire brushes! I follow the instructions to clean it with vinegar and even do it 2x a week. It is used so frequently that the tank is rinsed and refilled a lot. I have another Crane (the tear drop shaped one) and have NEVER had a problem with mildew/mold growing. This Duck has serious design flaws...it may be cute, but stick with the simple designs that can be kept clean!!
