- 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.
Perfect for my snails and shrimp! Works great!
I use this with crushed coral to keep my ph from crashing. I have a lot of South American fish and 3 large pieces of wood in my 75 g. community tank. Very hard water with almost no calcium and this helps a lot. Cory and the coop are an aquarists best friends.
This product works as designed. Highly recommended!
Does exactly what it is supposed to do
Made the fish tank water clear quickly.
