25 Club Piscine Super Fitness - Above Ground Swimming Pool - Owner’s Manual (03/2012)

After you or our technicians have completed the tests, you may need to correct your water balance.

Note : Elements are listed in order of importance, which means that if one component is modiﬁed, it could

affect the following one.

1) Total alkalinity

Total alkalinity is the sum of carbonates, bicarbonates and hydroxides—such as sodium and potassium—

in solution in the water. The more there are, the more alkaline the water is. The less there is, the more

acidic the water is. ALKALINITY IS THE SECOND MAJOR CAUSE OF WATER PROBLEMS,

FOLLOWING INSUFFICIENT CHLORINE.

To increase alkalinity, use sodium bicarbonate.

To reduce alkalinity, use hydrochloric acid.

Note : When alkalinity is too low, you will detect the odour of chlorine, your eyes will burn, algae forms, pH is

unstable and chlorine disappears rapidly. Be careful: your water will still appear very clear. When the alkalinity

is too high your skin will itch, chlorine no longer has an effect, pH is unstable and the water becomes cloudy.

2) pH

The potential of hydrogen, or pH, is the measure of acids and bases in the water. The more bases are in

the water, the more basic it is and the higher the pH. The fewer it contains, the more acidic it is and the

lower the pH. Ideal pH is between 7.2 and 7.6. You must not confuse acidity related to alkalinity with

acidity related to pH. Alkaline acidic water is corrected with sodium bicarbonate and water that is pH-acidic

is corrected with sodium carbonate.

To increase pH, use PH+.

To reduce pH, use PH-. Hydrochloric acid is not recommended as it will also lower the alkalinity.

Note : When the alkalinity is unbalanced, chlorine no longer has an effect and the water becomes cloudy.

When you adjust the pH, you must wait 24 hours before adding any other chemical products to the water.

3) Hardness (in-store test only)

Water hardness depends on the calcium and magnesium content of the water. Different factors affect the

results for water hardness tests, such alkalinity, pH and the amount of chlorine. It is therefore important to

balance these before testing for hardness.

To increase hardness, use calcium chloride.

To reduce hardness, use a water softener or any other product designed to eliminate water metals.

4) Chlorine

Chlorine removes bacteria from the water and destroys algae. Ideal chlorine levels are between 1 and 3 ppm.

Since there are many types of chlorine, seek the advice of a Club Piscine Super Fitness expert at your

local store.

Note : When levels are too high, chlorine burns the eyes, emits an odour and fades bathing suits. When

levels are too low, chlorine does not eliminate bacteria, water becomes cloudy and chloramines form. It

could also cause itchy skin. We recommend you dilute chlorine before adding it to your pool. Pour diluer le

chlore, utilisez un récipient et versez les produits dans l’eau et non l’eau sur les produits.
