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!**

Sanitisers disinfect pool water and protect bathers. The pool water should be tested daily to make sure it is properly balanced using pH+ or pH-. Good quality stabilized chlorine (if that is your chosen option) needs to be added to make the pool water safe. Also adding 'shock treatment' (oxidation) on a regular basis throughout the season is critical. Using a good shock treatment helps to avoid the water becoming dull and cloudy and prevents the development of any bacteria which have not been eliminated by the daily treatment.
