If the water in the pool is very dirty, e.g. due to high temperatures, heavy use of the pool, storms, etc., it can be cleaned rapidly by using Chlor Shock.
As a result of adding this product, the chlorine concentration increases sharply and kills algae and bacteria in the pool. Now add Liquid Flocculant: water can be then clarified by filtration. The pool must not be used for swimming while Chlor Shock is acting.
The recommended dosage is 90 g of Chlor Shock per 10 m3 of water in the pool. This dose can be lowered or increased depending on the degree of pollution.
