Soak copper sulfate, alum and bleaching powder in a vat for several hours in advance at night, and then sprinkle the medicine evenly into the swimming pool;
Copper sulfate can kill algae, alum can precipitate stolen goods, bleaching powder can sterilize, and then vacuumize the next morning to replenish some clear water to make the pool water clear and blue;
If there are bubbles and stolen goods on the water, you can use the swimming lane floating on the water, and two people can pull it from both sides of the pool to a corner, and then salvage it with a net.

1. Chemicals should be added wet, and different kinds of chemicals should have their own independent dosing systems, which should meet the following requirements.
The concentration of reagent solution should be 5% ~ 10%. But when hydrochloric acid is used, the concentration of the prepared solution should be 3%; The drug solution should be prepared at one time according to the daily dosage. When there are difficulties, you can allocate the usage of each session at one time; The dosing system should be equipped with or adopt devices or measures to fully mix and contact the drug solution with circulating water.
2. Coagulant should be automatically added in a continuous and constant proportion, and shall meet the following requirements
Dosage should be determined according to flocculation test data. In the absence of flocculation test data, the designed dosage can be 3 ~ 5 mg/L; When gravity dosing, it should be put into the suction pipe of circulating water pump; When pressure dosing, it should be placed on the outlet pipe of the circulating water pump in front of the filter.
3. pH sensor should be used to control the dosage of pH regulator and meet the following requirements.
The design dose should be 1 ~ 5 mg/L, and be adjusted according to Article 7.4. 1 of this regulation; When gravity dosing, it should be put into the suction pipe of circulating water pump; When pressure dosing, it should be put into the outlet pipe of circulating water pump before disinfection.
4. Algicides should be added intermittently according to the change of water quality in the pool and meet the following requirements.
The design dosage shall not exceed 1mg/L, and the dosing time and interval shall be determined according to the transparency of pool water and climatic conditions.
