Total Alkalinity: The level of Total Alkalinity is between 8° (80ppm) and 10° (100ppm).
The Total Alkalinity, expressed in French degrees (° f), is based on the concentration of carbonate and bicarbonate
ions. It sets the buffer power of the water. That is to say, the capacity of influence of an acidic or basic product on the
pH of the water. The higher the Total Alkalinity and the more difficult it is to vary the pH of the water.
TH: The ideal rate of water hardness is between 7 and 15 ° TH
Water hardness, its TH (Total Hardness), expressed in French degrees (° f), depends on the concentration of calcium
and magnesium ions. If the water is too soft, it will damage the heater, and if it is too hard, it will damage the pipes
and the ducts will become blocked with an accumulation of lime scale.

NEVER MIX BROMINE AND CHLORINE IN THE WATER: DANGER!
Choose either bromine or chlorine (hot chlorine foam).
Method:
Start by filling the spa with water from the tap.
Once full, test the Total Alkaline, pH and the ° TH.
Add pH stabiliser according to the recommended quantities. This will stabilise the pH until the spa is next
emptied.
If you are not using a pH stabiliser, correct the hardness of the water. (See manufacturer's values).
Add a steriliser: either bromine (recommended) in 1 diffuser, or chlorine.
The quantity of bromine must be checked after several hours of filter whereas chlorine can be checked
immediately.
The water will be perfect when the following values are met:
pH: 7.4
Bromine: 5 mg/L or Chlorine: 1.5 mg/L
