Water treatment
Specific studies on water balance have found a
correlation of equilibrium among the values of pH,
hardness, alkalinity: they must therefore be measured
frequently and then balanced.
Remember that:
• The pH must be between 7.4-7.8 to allow the bromine
disinfectants to be most effective and long lasting.
• The optimal alkalinity is in the range of 8-12.5°F.
• The hardness should not exceed 25°F. It can be kept
under control with sequestering agents specic or
limescale.
Only their perfect balance will guarantee water that is
clean, clear and low maintenance.

CHECKING THE WATER PARAMETERS
More information
TAP WATER AND WELL WATER
To ensure maximum hygiene and durability of the
minipool it is essential to pay close attention to the
quality of the water used.
Tap water guarantees microbiological purity and is
free of metal particles (not retained by the sand lter)
and organic substances. In contrast, well water often
contains traces of oxides, organic substances and
bacteria that can cause algae blooms and serious
damage to the minipool.
WATER HARDNESS
Water hardness is determined by the amount of
calcium and magnesium salts dissolved in the water.
Water classication:
........up to 7ºf = Very soft water
From 7ºf to 14ºf = Soft water
From 14ºf to 22ºf = Slightly hard water
From 22ºf to 32ºf = Fairly hard water
From 32ºf to 54ºf = Hard water
......more than 54ºf = Very hard water
(1°f = 10 mg calcium carbonate per litre of water)
WATER ALKALINITY
Alkalinity represents the quantity of some alkaline
substances (carbonates, bicarbonates, hydrates)
dissolved in water. Values lower than 80 mg/l or higher
than 125 mg/l can alter the pH uncontrollably making
maintenance of the water quality very difcult.
WATER PH
What is pH?
The pH indicates the concentration of hydrogen ions
(H+) in the water and represents its acidity or alkalinity.
Maintaining the pH within optimal values (7.4-7.8 -
neutral value) allows for:
• The well-being of those who use bathtub (the pH of
the skin, mucous membranes and eyes is slightly acidic,
close to 7, so this value meets this need)
• Duration of the minipool itself
• The best performance of water treatment products,
resulting in lower consumption.
