Dennerle Plants Liquid Conditioner is a liquid water conditioner for aquariums. It is used when tap water is added and helps condition the water to make it suitable for fish, plants, and other aquarium inhabitants. A water conditioner is particularly useful when changing the water, as tap water may contain substances that are undesirable in an aquarium. The Liquid Conditioner neutralizes chlorine and binds heavy metals such as mercury, lead, cadmium, and copper. This protects sensitive aquarium inhabitants and creates the foundation for stable water conditions. It is easy to use: The conditioner is added directly to the fresh tap water or into the aquarium during a water change. Dennerle Plants Liquid Conditioner is suitable for planted aquariums, community aquariums, and aquariums with sensitive inhabitants. It is safe for aquarium plants and fish and supports clean, balanced water care in freshwater aquariums. Dennerle Plants Liquid Conditioner+ liquid water conditioner for aquariums
