- 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.
Been using this for a few months it's really helped me with having healthy snails. Fish look great too!
I rest well knowing my snails and fish got their calcium fix.
Been using these for awhile in my shrimp tanks. Helps clear up water and I believe them to help strengthen their shells.
Wonder shells showed up in a timely manner.
My local water is low on KH, the wonder shells brought it up to a safer level (as well as GH).
I always use it in all my tanks, feels like it’s helping with water quality, I use it for many years with only positive results.
