15.99 20.99 £15.99 - £20.99
Shock dosing is important as it super oxidises the water and kills off resistant nasties as well as breaking down excess contaminants. Got an algae problem? This shock dose is extra strong so ideal.
No more fiddly measuring and mixing, just add the required amount of tablets to the dispenser and place in the pool. they will dissolve over several hours.
NEVER ADD OTHER CHEMICALS TO THE DISPENSER OR ADD THE SHOCK TABLETS TO A DISPENSER CONTAINING OTHER CHLORINE.
For a standard shock dose you will need to add 3 tablets per 1000lts of pool water. However if the water is cloudy or there are signs of algae starting then double the dose. In very bad cases you may even need to treble the dose. this is usually when algae is already established, a second dose may be needed after a day or two. When dealing with algae make sure you keep the chlorine level above 2ppm as it is used up quickly by the breaking down of the algae. See our algae busting guide on our web site for more info.
It is important to shock dose your pool around once every 7 to 14 days depending on the amount of use it has had, temperate and amount of sunlight.
