Chlorine Granules - Disinfection
To protect your health, ensure that your spa water is disinfected thoroughly on
a regular basis. This is particularly important in spas, as the high water tem-
peratures provide an ideal breeding ground for bacteria. To prevent water care
problems, there must always be sufficient levels of disinfectant in the water.
The use of Chlorine granules is the traditional method of disinfecting spas.
Chlorine granules dissolve quickly, without residues, and do not bleach the
surfaces. The granules are pH-neutral, i.e. the pH value of the water does not
change with the dosing of the granules.
Check the pH value using the 3 function test strips at least once a week, and, if
necessary, adjust it to 7.2 – 7.6. Add 10 g/m³ of Chlorine granules after each
bathing session. Let the circulation pump run for 10 minutes, and then check
afterwards using 3 function test strips that the ideal value of 1.0 – 1.5 ppm (mg/L).
is reached. If necessary, continue to dose. The granules are dosed directly into hot
tub water.
pH Up
and
pH Down
The pH value is the basis for reliable disinfection. The care products only work
perfectly when the levels are correct, meaning the water is not harmful to skin,
hair or eyes. The ideal pH value is between 7.2 and 7.6.
The pH value is influenced by various factors. For example it increases when fresh
water is added. Increasing the water temperature or using the jets changes the pH
value. Therefore, check the value at least once a week and, if necessary, increase
the levels using pH Up or decrease with pH Down. The granules are dosed directly
into the spa water.
