Taking care of a medium-sized swimming pool
First, measure the pH value of the pool, which should be between 7.2 and 7.6.
If necessary, adjust the pH so that the effect of chlorine is at its best
What is shock chlorination and how is it done with lifeguard recertification near me.
If the water in the hot tub or swimming pool is cloudy and the walls are slippery, have the pool shock chlorinated. Before shock chlorination, the pH value of the water must be between 7.0 and 7.4, because otherwise the chlorine will not react in the water at all. You can measure the pool’s pH value with a pool tester intended for that purpose. You can get the most accurate results with a photometric digital device. For example
Dispense approximately 150 g (1.5 dl) of Swimming Pool Chlorine , Quick Chlorine or Shock Chlorine per 10 m3 of water. So you need 15 grams of product for a cube-sized pool. The chlorine value of the water in shock chlorination is supposed to increase to about 4 ppm free chlorine, i.e. 4g/m³. It disinfects the pool and finally sets the pool’s free chlorine value to the correct value. To measure the amount of free chlorine in water, you need a water tester .
Shock chlorination should always be done on a new pool before putting it into use.
When should I swim after shock chlorination?
The chlorine value of the swimming pool should be 1–3 ppm free chlorine. The value can temporarily be higher immediately after dosing, and after shock chlorination you should not go swimming until the chlorine value is at least below 3 ppm, preferably close to 1 ppm. You can measure the values of the swimming pool with a digital pool tester.
Place chlorine in powder or tablet form in the filter basket of the surface valve according to the dosing instructions for the product. Water circulation must be used regularly.
If the pool is used a lot, the water is cloudy or the walls are slippery, do a shock treatment and dose about 150 g (1.5 dl) of Swimklor, Pikaklor, Snabbklor or Actioshock product per 10 m3 of water.
Measure the pool’s pH value and chlorine content weekly using the test kit. Adjust the pH if necessary before chlorination. Chlorine does not work with an incorrect pH value. Disinfection of the water should be regular to prevent the occurrence of bacteria and algae. The most common and effective agent is chlorine, but other pool chemicals can also be used. Read more about this further down in the guide.
Power tablet 4 is the most common and most pleasant to use in indoor swimming pools. It is available in large 200 gram tablets (“chlorine discs”). Correspondingly, in outdoor pools, you can use Long-acting chlorine discs or Multiklor discs .
Heavy use of the pool and higher water temperature consume more chlorine. Increase the dosage and perform a check measurement. If the water is cloudy and the pool walls are slippery, shock chlorination is needed. Dose Swimklor 150–200 g per 10 m3. Alternatively, the same amount of Pikachlor can be used, for example. Dispense a small amount, max. 100 g (about 1 dl) into the filter basket of the surface valve while the water circulation is on and spread the rest of the chlorine in the pool. It is recommended to dissolve the chlorine in warm water in a large bucket and then spread it in the pool. The pool must be open and the pool cover completely removed for at least 30 min after shock chlorination.
Similar can also be dosed directly into the warm pool water, if proper mixing is ensured. Please note that lumps left at the bottom can cause the pool plastic (liner) to turn white.
