Ten Tourmaline or Maifanitum Clay Mineral Balls

Ten Tourmaline or Maifanitum Clay Mineral Balls

Received these and let them sit in a cup of tank water for about 24hrs. then let them dry and wrapped them in a paper towel. Haven't got to use these yet because of cuttlebone already in the tank but once that is gone I'll be adding these.

Second time buying

These are perfect to toss in my shrimp tanks for my buddies to get their needed minerals. This was my second time purchasing for a new tank.

Works great!
