- Worth noticing
- Each calculator shows its formula, and the weekly routine says to clean the filter when pressure rises 8–10 psi above its clean reading.
Field notes
The maintenance section suggests testing chlorine and pH two or three times weekly, with a full water panel once a week. It also connects pump run time to the pump calculator and gives a filter-cleaning threshold of 8–10 psi above clean pressure. The water-target table notes that salt pools and plaster surfaces may call for different ranges, and advises following equipment manuals where they differ.
