Blue Planet – Tonic Salt

Blue Planet Aquarium Salt is obtained by evaporating sea water and contains many electrolytes not found in normal table salt.
Aquarium Salt adds natural electrolytes such as sodium, calcium, magnesium and chloride to fresh aquarium water. These electrolytes are essential for fish to maintain healthy gill function and osmoregulation. During periods of disease and stress, healthy gill function can be disturbed leading to loss of electrolytes.
