These shells are Wonderful for providing important Minerals /Electrolytes, Calcium Carbonate, and water hardness control, they aid in Chlorine removal and help keep aquariums clear, along with also boosting the overall well-being of the fish. Each shell oxygenates, aerates and aids in neutralizing harmful acids resulting from normal bio processes. Calcium and magnesium support fish, during stress, and help prevent disease due to acid buildup in the brain/body. They perform this by adding a constant supply of positive calcium and other positive mineral ions, which are depleted during Redox Balancing. Can aid in many health issues in fish, developed from lack of these important elements.
Contains: Calcium Carbonate/CaCO3+ cations, Chloride, Sodium, Magnesium, Sulfate, Potassium, Bicarbonate, Bromide, Borate, Strontium, Fluoride. ALL minor and trace elements in the exact ratio (with the exception of calcium) as found in the ocean.
