The use of trichlorine as a disinfectant ensures there is the right level of residual chlorine in pools.
Free residual chlorine (water with disinfecting properties) is essential for destroying any microorganisms that may enter a pool once the water has been disinfected.
It is recommended that the amount of free chlorine in a pool should never drop below 1 ppm.
Less than 1 ppm of free chlorine will enable bacteria and algae to grow in the water to bring about unhygienic and unpleasant conditions.
The exact amount of chlorine needed to maintain 1 ppm of free chlorine will depend on the number of swimmers, the sunlight and the temperature of the water, as well as atmospheric conditions in the case of outdoor pools.
As trichlorine contains a stabiliser in its formulation, it prevents the product from evaporating and the pool from running out of disinfectant
