Tourmaline Mineral Balls give better water quality by deionizing water and provide essential minerals for neocaradina/caradina shrimp growth. These benificial minerals improve molting failure, enhance survival rate of baby shrimps, as well as brighten body color of the shrimps.
I've had these for a while. Not entirely sure what they do but they look nice in my tank and the shrimp graze on them 🥰
Great product, the same as the pictures, fast delivery and easy to deal with
Slow release of minerals for healthy shrimp would recommend
