Key Benefits: Enhanced Shell Growth: Rich in calcium, these shells support the development of strong, healthy exoskeletons in both shrimp and snails. Dual Functionality: The shells can be consumed directly by your invertebrates or left to gradually dissolve, enriching the water with vital minerals that increase hardness—aiding not only shrimp and snails but also benefiting livebearers and aquatic plants.

Regular replacement is recommended to ensure a consistent supply of these essential nutrients.Some loose guidelines: Add 1 shell per month or after each water change, whichever comes first. Monitor hardness in aquarium and adjust use accordingly.
