Chlorine Reducer for hot tubs is a specialised chemical solution designed to safely lower the chlorine levels in your spa or hot tub. Maintaining the correct chlorine level is crucial for water sanitation, but sometimes the chlorine levels can become too high due to overuse of sanitiSers or improper chemical management. Chlorine Reducer helps bring those levels back into the ideal range, ensuring that your hot tub water remains safe, comfortable, and irritation-free.
Prevents Skin and Eye Irritation: High chlorine levels can lead to irritation of the skin and eyes for bathers. A chlorine reducer helps maintain comfortable and safe water conditions, reducing the risk of discomfort during your soak.
Restores Water Balance: Excess chlorine can throw off your water’s chemical balance, affecting pH, total alkalinity, and overall water quality. Using a chlorine reducer brings chlorine back into the ideal range (typically between 1–3 ppm) to ensure water remains clean, clear, and balanced.
Prevents Damage to Hot Tub Equipment: High chlorine concentrations can corrode hot tub components like heaters, jets, and pipes. By using a chlorine reducer, you protect your investment and keep your hot tub in top condition.
Easy to Use: Chlorine reducer is simple to apply, typically available in granular or liquid form. It works quickly and efficiently to neutralise excess chlorine, allowing you to enjoy your hot tub without worrying about chemical imbalances.
Chlorine Reducer is a chemical used to lower free chlorine levels in hot tubs, spas, and pools safely. It neutralises excess chlorine to bring water back into the safe and comfortable range.
Water feels harsh or smells strongly of chlorine
Skin or eyes are irritated
High sanitiser levels after shock treatments or heavy chemical dosing
Test the free chlorine level using test strips or a digital tester.
Calculate the required dose based on your hot tub or pool volume and current chlorine level.
Add the product to the water (usually pre-dissolved in a bucket for best results).
Run the jets/pump to circulate the water evenly.
Retest the chlorine level and adjust further if necessary.
Usually works within minutes, but full circulation ensures even distribution.
Retesting after 15–30 minutes is recommended.
Yes — too much chlorine reducer can lower chlorine to unsafe levels, allowing bacteria or algae growth. Always retest and adjust carefully.
No — Chlorine Reducer primarily neutralises chlorine; it has minimal impact on pH, alkalinity, or hardness.
Hot tubs/spas: 3–5 ppm
Swimming pools: 1–3 ppm
If your level is above this, Chlorine Reducer can safely bring it back down.
Yes — it reduces both chlorine and bromine levels, as they are both halogens and react similarly with reducer chemicals.
Yes — many products labelled as "Dechlorinator", “Chlorine Neutraliser”, or “Chlorine Remover” use the same active ingredient (sodium thiosulphate).
