Adding Chlorine To Your Pool
Assuming that the total alkalinity is at the right level and the pH is correct, chlorine can be added. The amount of chlorine to add depends on the present chlorine level and the type of chlorine used. Refer to the manufacturers instructions for quantity.
As discussed previously, chlorine degrades rapidly under the influence of UV light. For this reason chlorine should be added only in the late afternoon or early evening, when it can dissolve and mix thoroughly before the damaging sun’s rays can affect it.
The chlorine should be evenly scattered/ poured around the pool or poured slowly in front of the return flow jets to ensure rapid and even distribution.
Chlorine should be kept at a level of 1.0-3.0 ppm to ensure sufficient sanitation. If you are using a Pool Wizard, a level of 0.5 ppm is required. This combination will provide a far superior sanitation to chlorine alone.
If the pool has very high levels of contamination or there is a strong smell of chlorine around the pool, you may need to shock treat the water. This involves adding large quantities of non-stabilized chlorine (or non-chlorine oxidizers) to the pool, which rapidly destroys the offending matter.
