Tourmaline Mineral Spheres made of tourmaline stone are a must have for freshwater shrimp, crayfish, snails, bettas and goldfish. Each ball measures approximately 25mm in size. They slowly and safely release minerals and elements. Lasting for 1–2 years these balls slowly break down releasing elements such as: aluminum, iron, magnesium, sodium, lithium, potassium and many other essential minerals.

Benefits to aquatic life

Improved shrimp and crustacean molting, enhanced colours, higher breeding & survival rates as well as an overall improvement in growth and health.

Benefits to aquarium water

Purification by de-ionization and stability of pH. GH can be raised if used at a high dosage.

Benefits to soil and plants

Plant absorption of elements when the balls are pushed into the soil around the plants. In addition, they also provide a large surface area for beneficial bacteria to grow on. If placed on the surface of the substrate the spheres provide an excellent surface area for algae to grow which shrimp and other aquatic life can graze on.

DIRECTIONS 1 ball per 8 litres of water.
