Before trouble starts, give your pool or hot tub a regular shock treatment - don't wait until you have cloudy or green water. Chlorine shock helps prevent and remove algae, and destroys swimmer wastes. May be used for regular disinfection.
Preventative shocking is always the correct action, so make sure you always have plenty of shock in stock!
**There is currently a shortage of Chorine Shock UK-wide, and we only have limited stocks of 5kg and 2kg tubs. If you require a 1kg tub, please consider ordering non-chlorine shock instead - does the same job, just without the chorine!**
