Fortified Isopod Substrate w/ Calcium

We have blended the most effective and complete isopod substrate on the market! It's the perfect combination of all natural soils, hardwoods, leaf litters and moss fortified by calcium.

Calcium is essential for many species of isopods and pill bugs. Not only will your animals feed on this as needed, but it also acts as a pH neutralizer and odor/moisture absorbent. 

Journal of Crustacean Biology:

"Terrestrial isopods have high calcium requirements because of both the development and frequent molting of their mineralized cuticle (Ouyang and Wright, 2005), and also the need for a gut pH suitable for microbial cellulolytic activity and proper digestion of plant polysaccharides (Zimmer, 2002)."
