BioBedding Hermit Crab is the perfect substrate for your bioactive hermit crab enclosure! This substrate is a unique blend of ingredients designed to jump-start the bioactive environment. It helps to maintain a proper level of humidity， yet retains moisture in a way to easily provide humid hides， support burrowing and foster a community of cleaner invertebrates and beneficial organisms. How to Prep This bag has already been mixed with Quikcrete Play Sand! This means no mixing and no mess for you! Add mixture to the enclosure to a minimum depth of 3 times the height of your largest hermit crab. It is likely that no water will need to be added， but if the substrate does not hold its shape for burrowing， slowly add dechlorinated water until it is "sand castle" consistency. Clean up Crew Springtails and Isopods help keep your tank clean! They eat droppings and other unwanted things that occur in terrariums. We recommend dwarf whites or Porcellionides pruinosus isopods due to their small size and ability to survive in tropical environments.
