Fi-Cor Spa Shock contains approx 15% more available chlorine than standard calcium hypochlorite. It dissolves very quickly to form free chlorine to kill bacteria & break down organic contaminant in the water that cause eye sting & bather discomfort.

When filling your spa for the first time (commissioning) or when refilling after it has been empty for a period, it is strongly recommended that a shock chlorination should be carried out on the cold fresh water. Fi-Clor Spa Shock are ideal products for this purpose as they are unstabilised chlorine donors & will deliver the maximum effectiveness.

The free available chlorine level should be taken to either 25mg/l (ppm) for a minimum of two hours, or 50mg/l (ppm) for a minimum of one hour.

While the spa is being chlorinated to these high levels, the water must be allowed to flow to all parts of the system, regularly monitoring the chlorine residual to ensure that it does not fall below the specified level at any time. Where an air blower is fitted, it should not be run for the first 15 minutes to minimise the formation of aerosols (fine spa water mist).

During shock chlorination, the p H should be maintained within the range of 7.2
