AquaSpa is a chlorine and bromine-free spa sanitation system developed by Lo-Chlor. The range covers sanitiser, shock, clarifier, water balancers, and filter and pipe care for residential spas, hot tubs and swim spas.
The 1kg is the practical stock-up size for households that use the spa regularly. AquaSpa Spa Shock is a non-chlorine oxidiser that clears the organic compounds which build up between weekly sanitiser doses: body oils, sweat, cosmetics and the residue that causes cloudiness, odour and surface foam. The 1kg provides approximately 6 to 8 months of weekly treatments in a standard 1,500L spa.
Spa Shock works alongside the Spa Sanitiser, not instead of it. The sanitiser handles bacteria and pathogens. The Shock handles what the sanitiser cannot break down. Used together weekly, they keep the water genuinely clean rather than just chemically balanced.

❓ FAQ▾
How long does the 1kg last?▾
At 10g per 1,000L weekly in a 1,500L spa, the 1kg provides roughly 66 treatments, or over a year of weekly use. More frequent dosing or larger volumes will reduce that.
Is Spa Shock the same as the sanitiser?▾
No. Spa Sanitiser handles bacteria and pathogens. Spa Shock is an oxidiser that removes organic residue the sanitiser cannot break down. Both are required.
Can I add Shock and Sanitiser together?▾
Yes. They are compatible. Dose both on the same day with the pump running.
Do I need Spa Kleer as well?▾
Spa Kleer is a clarifying agent for oils and body fats that cause visible haze. Shock breaks down organic compounds and Kleer clears the remaining oils. They do different jobs and work well together.
