Guide to Pool Cleaning: Detailed Explanation of Salt Acid, Bleach, and Chlorine Application

Contact: Does soaking for one hour in 10% hydrochloric acid once a season and then in bleach extra suffice?

Advisor: Hello
Advisor: Yes

Contact: Do we always need to use bleach as well? Which bleach should be used?

Advisor: Bleach

Contact: Which bleach should be used?

Advisor: Whatever you find in the store

Contact: Laundry bleach, for example? Is this step absolutely necessary?

Advisor: No, I don't think so

Contact: But is it not necessary to soak in hydrochloric acid once during the season?

Advisor: If your water is not particularly dirty, it is not necessary

Contact: The values measured on the Zodiac TRi Expert always differ greatly from the manually measured values?

Advisor: Can you give examples of values?

Contact: 850 mV and manually 0.6-1

Advisor: They are not the same measure. Is there a standard solution? If yes, soak the probe in it and check the value

Contact: The manual measurement is in mg/l

Advisor: The redox measurement does not have a direct correlation with mg/l. A value of 850 mV seems correct

Contact: Chlorine is constantly missing? Could salt deficiency be the cause?

Advisor: Check if your electrolytic cell is producing chlorine. A white spot will appear

Contact: Where will a white spot appear?

Advisor: Test your redox sensor like this as well: Link
Advisor: On the electrolytic cell

Contact: I don't understand where the spot is formed and visible

Advisor: Do you know where the electrolytic cell is located?

Contact: The probe is six months old

Advisor: To be sure, it needs to be tested

Contact: No. When I press the Boost button, mist is produced

Advisor: So the cell is working
Advisor: Why do you think there is not enough chlorine?

Contact: Could it be that in normal operation, not enough chlorine is produced in the heat and only the Boost function provides a solution!
