Ruby Reef’s Hydroplex is an extremely broad-spectrum treatment for external fish parasites and pathogenic bacteria, and is perfect as a dip for new arrivals. Hydroplex quickly penetrates into the fish's surface tissues and removes active parasites, bacteria, and fungus that may be attached to your new fish. Hydroplex removes the damaging parasites and also helps to heal open wounds. It can be used at a lower dose in hospital and quarantine tanks to prevent infections and aid in the recovery process.
