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.

Wonder Shells

If you have snails then you need this product. Calcium is vital for snail shell health and Wonder Shells provide this in an easy, no hassle way.

Wonderful Wonder Shells!

I bought some wonder shells as I was looking to add a calcium supplement to my snail and shrimp tank, because I noticed one of my nerite snails had a damaged shell just after I bought him. His shell has since healed wonderfully after I began putting these in his tank. I have mystery snails and cherry shrimp as well, and they seem to love the wonder shells too! 5 out of 5 stars, definitely get these.
