Technical characteristics

HTH SPA: Chlorine-Free Shock for Green or Cloudy Water

This powdered product is perfect for maintaining your spa water. It helps clear up cloudy and green water and also acts as a Bromine activator. It is suitable for all types of water, even very hard water.
You can use it without worry regardless of the water's pH and works with all types of filtration.

Compatible with: bromine or oxygen-based products.

The Chlorine-Free Shock, as the name suggests, disinfects your water without chlorine, and therefore, does not produce chloramine or isocyanuric acid (stabilizer).
It is a very powerful oxidizer that effectively eliminates bacteria and other particles left by hot tub users.
It has a rapid dissolution, leaving no residue in your hot tub.

How to Use HTH SPA Chlorine-Free Shock?

Before using HTH Spa, make sure your spa's filtration is running. Carefully distribute the product directly into the water, covering as much surface area as possible. (Be mindful of the wind direction to avoid product splashing into eyes)

If you need to clear green or cloudy water, 20g of Chlorine-Free Shock per m3 of water should be sufficient.
If using it as a Bromine activator, then plan for 15g per m3 of water every two weeks at least 1 hour before bathing.

What Precautions to Take When Using HTH Chlorine-Free Shock Safely?

The Chlorine-Free Shock:

Must not be mixed with other products
Does not dissolve before use
Reacts violently when in contact with a small amount of water
Should only be used with a single, completely dry scoop
Must not be poured into the water when bathers are present
Should be stored dry, at a daily average temperature not exceeding 35°C

Caution, it is a highly corrosive product, keep out of reach of children. Read and strictly follow the instructions on the product label before use.

Produit mal revisser et périmé en décembre 2025. Nous nous sommes rendus à l entrepôt. La personne de l accueil nous a indiqué que si le produit était à l abris de la lumière et contenant bien fermé. Cela ne risque rien. Ce produit sera terminé dans 1 an et demie voir deux. Spa de 2m3 qui est mis en hibernation.
