10. WATER TREATMENT
Once the pool is filled, the water quality will naturally begin to degrade due to pollutants carried in by
bathers (bodily secretions, but also twigs, grass, earth, sand, etc. stuck to their feet and their skin), as well
as pollutants carried by the wind (leaves, petals, pollen), and insects.
The water will therefore need to be replaced periodically. The frequency of replacement will depend on the
water temperature, the bather load, the length of the daily filtration window and the use of pool chemicals.
Filtration slows the natural degradation of water by trapping tiny particles (from a few millimetres across to
a few tens of microns).
The length of the daily filtration window necessary will mainly depend on the level of pollution carried into
the water and the water temperature. For information purposes, while the pool is in daily use, the minimum
filtration times recommended are as follows:
• Water temperature of 20°C: 5 hours per day;
• Water temperature of 25°C: 8 hours per day;
• Water temperature of 30°C: 12 hours per day;
These recommendations are valid for the original filtration group supplied with your POOL’N BOX JUNIOR.
The cartridge in your filter is not compatible with most flocculants (chemicals formulated to remove the
tiniest particles suspended in the water).
Filtration alone is not sufficient to eliminate any health risk associated with the presence of micro-organisms.
To keep the water sanitary, and limit the frequency of replacement, the water needs to be treated with pool
disinfectant products.
10.1 Maintaining pool water quality
Correct use of your pool requires optimal water treatment. Clean the cartridge regularly (refer to the
cleaning protocol described in the filtration manual) and make sure that the daily filtration window is long
enough (see the previous paragraph).
To fill the pool, use drinking water the properties of which are compatible with the liner. Use of well water
or water from a private source is prohibited.
The pool water must be tested and treated regularly in order to maintain water quality. The frequency of
treatment will vary depending on the pool’s situation, in addition, the user should familiarise themselves
with the use of the various products that may be needed to treat the pool and maintain water quality. During
the winter season, an algaecide and/ or winterizing product may be added to the pool (not supplied).
Test the pool water properties regularly to ensure that they remain within the following limits:
• if the pool is treated with Chlorine, pH between 7.0 and 7.4, free Chlorine concentration between 0.7
and 1.2 mg/L;
• if the pool is treated with Bromine, pH between 7.6 and 8.0, Bromine concentration between 1 and
2 mg/l.
The TH (calcium hardness) which measures the calcium hardness of water, that is, the concentration of
calcium ions, and the TAC (total alkalinity), that is, the concentration of Hydrogen Carbonate ions, must be
between 100 ppm and 250 ppm. A high TAC and/or TH could lead to the deposition of calcium deposits on
the liner. A lower TAC or TH could make the water aggressive and lead to the corrosion of metallic parts
of the pool.
Waste water from the pool should be disposed of in accordance with the regulations in effect in the area in
which the pool is installed, these may vary.
