The quality of tap water in our homes doesn't always allow for direct use in aquariums. Active chlorine compounds are often used in water treatment to eliminate pathogenic flora. Active chlorine, even in small amounts, can negatively impact the health and well-being of aquarium inhabitants. Heavy metals also have an equally significant impact on the health of aquatic organisms. Even at low concentrations, they cause behavioral changes in fauna by disrupting the secretion of neurotransmitters. Gedoku Water Conditioner isa high-quality water conditioner.
