📋 How it works▾

Lo-Chlor Shock n Swim is a rapid, non-chlorine shock treatment for pools and spas — eliminating organic contaminants and combined chlorine build-up quickly, with a 15-minute re-entry time after treatment.

Organic matter from swimmers (body oils, sunscreen, sweat) and the environment (leaves, dust) reacts with chlorine to form combined chlorine (chloramines) — the cause of that distinctive pool smell, eye irritation and reduced sanitiser effectiveness. Shock n Swim's potassium monopersulphate formulation oxidises this organic load rapidly without adding more chlorine or leaving your pool unusable for hours.

Lo-Chlor Shock n Swim details

  • Non-chlorine shock — oxidises organic contaminants without additional chlorine
  • 15-minute re-entry time after treatment
  • Reduces combined chlorine (chloramines) and restores water clarity
  • Suitable for pools and spas
  • Available in three sizes: 500g, 1kg and 5kg
  • Active constituent: potassium monopersulphate (MPS)

Choosing your size: The 500g is ideal for spas or as a single treatment for small to medium pools. The 1kg is the most popular size for regular residential pool use. The 5kg is economical for large pools or owners who shock regularly.

For a non-chlorine shock in pools that already use the AquaFresh non-chlorine sanitiser system, AquaFresh Performance is the dedicated non-chlorine shock designed for that system. For a combined system reboot, AquaBoost is the Lo-Chlor potassium peroxymonosulphate shock option.

❓ FAQ▾
What's the difference between chlorine shock and non-chlorine shock?▾
Chlorine shock (super-chlorination) raises the free chlorine level dramatically to burn off organic matter and kill algae. Non-chlorine shock (like Shock n Swim) uses oxidation to break down organic compounds without raising chlorine levels. Non-chlorine shock is gentler on pool surfaces and equipment, and allows swimming much sooner.
Why does my pool smell like chlorine if I have enough chlorine?▾
That 'chlorine smell' is actually chloramines — combined chlorine formed when free chlorine reacts with organic matter. It indicates your chlorine is being consumed by organic load. Shock n Swim oxidises the organic matter, freeing up chlorine and reducing the chloramine smell.
Can I use Shock n Swim instead of regular chlorine shock?▾
Yes for organic load management. But if you have an active algae problem, chlorine super-chlorination is more effective for killing algae. Use Shock n Swim for regular oxidation maintenance; use chlorine shock when treating actual algae outbreaks.
Which size should I buy?▾
For a standard residential pool used regularly through summer, the 1kg provides approximately 5 treatments at the regular maintenance dose. The 500g is ideal for testing the product or for spa-only use. The 5kg is economical for weekly dosing programs or large pools.
