KL works best in shallow containers and not in those bulk bags or mesh. Spray the distilled water over the litter...about 5 sprays to start so you don't over load it and I use those small rubbermaid containers that are about 2x5x3. 2 inches deep is great and as long as you have room you can get those cheaper at Dollar Stores. For a buck you can get any size container to hold your KL.
