SunGrow Mineral Rocks - Calcium Supplement for Fishes

I am always looking for something new to try in my son's fish tank. We don't have your normal pet store fish. My son likes to catch his fish from the local creeks and keeps them as pets. Right now he has a bream and a turtle he caught in the tank.When they get too big for the tank he turns them loose and catches more. When I saw that they would help with purifying the tank water and treat they offered minerals that the fish needed I thought they would be a good addition to the tank. The bag comes with several different sized rocks. They can range from small to medium. They look like normal everyday rocks. But at least with these, I don't have to worry about contaminating my tank or having to treat them before adding them . They look nice in the bottom of the  and it gives the turtle something else to push around in the tank. 

I received this product on a promotional discount for my honest review. Regardless, all opinions are 100% my own based on experiences with said product.
