TREATING THE WATER
WARNING: The information contained in the following sec-
tions about Water Treatment and Filtering are generalities. If
you acquire any of these materials, we recommend that you
follow the instructions which accompany the given product
closely.
In order to keep the pool water clean and clear, you must use
a disinfecting agent. Its role is to kill off any micro-organism
and bacteria contained in the water and to prevent algae
growth. Disinfection involves two main factors: the water's
acidity (pH) and its chlorine content.
The pH value indicates whether a given body of water is acid
or alkaline and to what degree.
The water in a swimming pool must have a pH value rang-
ing between 7.2 and 7.6. Beyond this level, the action of
chlorine is considerably inhibited and the water can become
irritating. If the pH value is below 7.2 the water is aggressive
and can be the cause of corrosion of the metal parts of pool
appliances.
CHLORINE CONTENT
This is measured in milligram-liters (mgl) of active chlo-
rine. This value must be situated between 0.4 and 1 mgl.
The water must be tested for pH and chlorine values by
colorimetric analysis, using an analysis kit. We strongly
recommend that you replace the kit's reagents once a year.
Observe the instructions provided with the kit.
I - PUTTING THE POOL INTO SERVICE
When reopening the pool or refilling it with water, the follow-
ing operations should be performed:
1-pH
Check the pH value, which should be situated between 7.2
and 7.6. Use the analysis kit. If the pH value found is higher
than 7.6, use "pH MOINS" (pH decreaser);
If the pH value found is lower than 7.2, use "pH PLUS"
(pH increaser).
Comply with the dosages indicated on the package.
2-Chlorine
Check the active chlorine value, which must be at least
0.4mgl.
If the value found is lower than this, use chlore rapide (rapid
action chlorine) in granulated or tablet form in order to rapidly
rebuild the minimum active chlorine level.
For normal operating, place the 200g or 600g chlore lent
(slow action chlorine) chlorine cakes in the skimmer (200g for
25 m3 water). The slow distribution of this chlorine will keep
the chlorine values of your pool stable for approximately 8 to
10 days.
WARNING: It is very important that chlorine products be
placed exclusively in the skimmer.
3-Stabilizing agent
Sun rays and warm water temperatures decompose chlo-
rine, largely imparing its disinfecting capacity and leading to
increased chlorine requirements. In order to eliminate this
problem, when filling the pool, use the stabilisant stabilizing
agent.
This operation need not be renewed as long as the pool is
not drained. Please see the instructions provided with the
technical description of the product.
Please note that addition of too much stabilizing agent will
have a chlorine-inhibiting effect. In this case, it suffices to
eliminate 2 to 3% of the water in the pool every week, prefer-
ably during cleaning operations.
4-Water-softening agent
If using hard water (containing lime), initial treatment is very
important. In order to prevent lime deposits in the pool or in
the filter, use a water-softening or anti-liming product, follow-
ing the instructions on the package.
II - MAINTENANCE
When all the above operations have been successfully per-
formed (pH, Chlorine, stabilizing agent and anti-liming agent), it
is importante to ensure proper maintenance:
1- Once a week, control pH and chlorine levels.
The pH value is generally quite stable, but it can be modified by
adding water to the pool and by the use of organic chlorine (e.g.
Javel water or Clorox), which often raises the water pH level and
decomposes rapidly.
2-Check chlorine level.
If it has dropped below 0.4mgl, use chlore rapide (rapid
action chlorine).
3-Check
(slow action chlorine; 200g or 600g) in the skimmer. Do not
wait for them to dissolve entirely before adding the new ones.
III - ANTI-ALGATE TRETMENT
1-Preventive treatment:
At the dosage prescribed above, chlorine also acts as an
algicide. Stormy weather, frequent use of the pool, faulty fil-
tering are factors which can increase the rate of algae forma-
tion, resulting in slippery, slightly greenish walls. In this case,
do not hesitate to apply a high chlorine dosage and leave the
filter on around the clock.
2-High-dosage algicide:
If in spite of this measure the algae do not disappear, use a
very active algicide.
IV - FLOCCULATION
Certain very fine organic particles may not be sufficiently fil-
tered by sand filter action. The use of a flocculating agent will
enhance the efficiency of filtering, thus eliminating all sus-
pended particles in pool water.
Start by putting the flocculating agent into the filter. If it turns
out that this is insufficient, perform flocculation directly in the
pool itself. Observe the instructions on the package.
V - WINTER CARE
At the end of the season, after a thorough cleaning operation
and high-dosage chlorine treatment, use the "HIVERNAGE"
(wintering) product in the prescribed doses.
