The Standard chemistry package is a starter kit for gentle and effective chlorine-free water maintenance in a hot tub and smaller pool. The water stays clean, clear and free of chlorine odour, gentle on the skin, hair and breathing. For the best result we recommend a combination with a properly set ozone generator or UV lamp, which significantly support the effect of chlorine-free chemistry.
