Keeping pool water in good condition goes far beyond adding chlorine now and then: it is a balance of several chemical parameters that must be checked and adjusted regularly, above all in the swimming season.

Parameters to monitor

The water's pH must be kept in a narrow range (roughly between 7.2 and 7.6) for the chlorine to be effective and not irritate skin or eyes; the chlorine level must be adjusted according to use and temperature; and periodically it's wise to check alkalinity and stabiliser level, which affect chlorine's effectiveness under sun exposure.

Physical maintenance tasks

Besides the chemical treatment, complete maintenance includes brushing walls and floor, cleaning skimmers and baskets, checking the filter's operation (with periodic backwashing) and cleaning the waterline, where visible greasy dirt accumulates.

Indicative price of the monthly service

As a reference, professional monthly maintenance of a standard domestic pool (weekly visit in season) usually runs around €80-150/month in high season, with chemicals included or billed separately according to the agreement with the client.
