    Premium Chemistry Package – Chlorine-free Set for Hot Tubs

    Maximum cleanliness without a chlorine odor even with frequent use. An extended chlorine-free package with disinfectant 3 L, pH MINUS 1.4 kg, OXI Active 0.8 kg (oxygen shock), and a DUKE pH drop tester. Ideal for regular operation, weekend high-traffic bathing, and small pools.

    Synergy with ozone/UV: For the best result, have a properly configured ozone generator or a UV lamp. Ozone/UV significantly boosts the effectiveness of chlorine-free chemistry—the water stays consistently clean, crystal clear, and free of the typical chlorine smell.

    How to proceed correctly 

    1

    Circulation and filtration

    During normal operation, maintain filtration according to your hot tub manufacturer’s recommendations.

    2

    Measure pH

    Use the DUKE drop tester to check the pH value.

    3

    Adjust pH

    If pH > 7.4, dose pH MINUS according to the label. Let it mix by circulation and measure again.

    4

    Chlorine-free disinfection

    Add the recommended amount of chlorine-free disinfectant (as per the label) and let the water circulate.

    5

    Weekly shock / after heavy use

    apply OXI Active as per the label—ideally after weekend operation or when the water is cloudy/odorous.

    6

    Synergy with ozone/UV

    For oxidation and disinfection 1–2× per week; more often after topping up or heavier use.

    Tip: Dose OXI Active in the evening after bathing, keep the filtration running—the water is usually more crystal clear in the morning.

     

    Is chlorine-free disinfection as effective as chlorine?

    Yes—at the right pH and dosage, and especially in combination with ozone/UV, it keeps the water clean and hygienic—without the typical chlorine smell.

    How often should I measure pH?

    We recommend 2–3× per week, always after topping up the water and after heavy hot tub use.

    Does the package work without ozone/UV?

    Yes, but ozone/UV significantly improves the result (lower chemical consumption, more stable cleanliness). If you don’t have it, consider adding it.

    Is it safe for materials (acrylic, stainless steel, seals)?

    Yes, at the right pH and dosage. Balanced pH protects materials and extends their service life.

    What is OXI Active for if I already have a chlorine-free disinfectant?

    OXI Active is an oxygen oxidant for shock polishing—it removes organic impurities and helps restore sparkle, especially after heavy use.

    How often should I use OXI Active?

    Usually once per week or after intensive use. Always dose according to the label and water volume.

    Can this package handle a small pool as well?

    Yes, the products are also suitable for small pools. Dose according to the volume and the labels.

     

    Technical and safety notes

    Dosage: Adjust to the water volume and current condition; follow the labels.
    Storage: Keep dry, out of reach of children; protect from frost and direct sunlight.
    Safety: Use protective equipment as indicated on the labels. Do not mix with unrelated products.
