  • Made of Natural Materials
  • Easy to Use 
  • Adds Essential Minerals to Aquarium Water

These shells are great for adding hardness and minerals into your aquarium water. If you need more minerals for snails, shrimp, plants, goldfish or African cichlids etc, Wonder Shells are a good place to start. They are extremely easy, just drop it in your aquarium. Over time, Wonder Shells will completely dissolve into your water. Simply replace them when they do. Please note that Wonder Shells do not raise the pH level of your aquarium.

My Shrimp are happy

This is my first time using these little wonder shells and I'm happy so far! I felt my 10g was lacking and my shrimp were losing color and less active. So I tried this and they are already doing better. They are grabby grabbing away and looking good!
