1kg CrystalClear Chlorine Shock Granules for Hot Tubs & Swimming Pool23
1kg CrystalClear® Ultimate Chlorine Shock Granules. A highly effective, market leading, traditional shock treatment product, these calcium hypochlorite granules have an available chlorine level of a minimum of 70% making them a perfect chlorine shock for pool and tub water problem solving. Granular Shock Chlorine is very effective at restoring sparkling water from algae infestations and also destroys other waterborne bacteria, germs and other micro-organisms that can be present in warm pool and hot tub water, especially after high bather load.

Granular Shock Chlorine should be pre-dissolved in a clean bucket or warm water until the granules are fully dissolved. This can then be poured around the pool or hot tub while the jets/pumps are running to aid distribution in the water. Do not use more than 100g of granules per 10 litres of warm bucket water. To properly shock bathing water a chlorine level of approx 10mg/l or 10ppm should be achieved.

This level will slowly diminish as it destroys the organic matter, germs, bacteria or any algae in the water and will diminish even quicker if the water is exposed to sunlight. Once levels have reached their optimum for bathing again 1-3mg/l or 1-3ppm for pools and 3-5mg/l or 3-5ppm for spas and hot tubs safe bathing can then be resumed. It maybe necessary to check other parameter are in place after shocking, such as pH and Alkalinity levels to get the best results from any further chemicals used in the pool or tub.

Chlorine shock can sometimes increase pH levels slightly but this can easily be adjusted by the addition further water or by using a pH minus/decreaser product. It is recommended to shock pool and tub water every few weeks when a pool or tub is in daily use and preferably a day before you plan to use it for bathing. This allows time for correct bather level adjustments if necessary.

The shocking process may be expedited depending on the state of the water and the amount of contaminants in it. The more dirty, contaminated or algae the water contains, the quicker the chlorine shock will reduce to near normal levels. Cleaner pool and hot tub water may take longer for chlorine levels to reduce back to normal after a shock but again this can be expedited by adding further plain water or exposing the water to sunlight. Ideally a 24hr period should be allowed for the chlorine shock to work its magic before adjusting levels and commencing bathing. It may be necessary to brush the floor and side walls of a pool or hot tub with a soft pool brush to agitate a severe algae infestation (see images).
