  • 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.

Wonder Shells are convenient and useful.

I have multiple community aquariums, all with various shrimp and snails. I have found Wonder Shells ensure my invertebrates are healthy and thriving as well as providing balanced TDS levels for my tanks.

It works

I've used Wonder Shell a lot over the last year. CoOp is a reliable source with a better price than Amazon. I have gotten a lot of fakes from Amazon, but never from CoOp.
