Composed of natural elements, the Wonder Shell Natural Minerals Water Conditioner enriches aquarium water with essential minerals and electrolytes. Each shell works to oxygenate, aerate, and counteract harmful acids in the tank, while also supplying invertebrates with a readily accessible calcium source for strong shell development. Designed in the likeness of a scallop shell, the Wonder Shell adds a charming, decorative touch that blends seamlessly with your aquariums aesthetic. Available for purchase at shop.morphmarket.com.
