Standard Chemistry Package – Chlorine-Free Kit for Hot Tubs

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.

Package contents

Procedure

• Maintain circulation and filtration according to the hot tub manufacturer’s recommendations
• Measure the pH with the DUKE tester
