Ideal Water Balance for:


This should be maintained between 1.5ppm and 3.0ppm depending upon the temperature of the water. The warmer the water, the higher the chlorine level needs to be. Do not exceed 3.0ppm. It is also important that a minimum level be maintained otherwise ear, eye and skin infections from bacteria can result.


This should be maintained between 7.2 and 7.6. This is the ideal range for swimmer comfort and chlorine performance.

Total Alkalinity

This should be maintained between 80 and 125ppm. Ideally, keep the level around 100ppm at all times.

Ideal Water Balance for:

Calcium Hardness

This needs to be maintained between 175 and 250ppm. If the level is too low, the water will attack the surface of the pool and degrade concrete, tiles and fibreglass. If the pool is running with a magnesium additive it is important to check the Total Hardness. If all the levels are in the correct range, then the water is balanced. This will eliminate the risk of surface or equipment damage, sore and irritating eyes and skin, potential for water carried illness, algae build up and scale formation.

Salt and/or Mineral Levels

These must be tested and maintained at all times to prevent damage to the chlorinator and to provide the correct level for maximum sanitiser production.


This prevents the loss of chlorine to sunlight and should be maintained around 50ppm. Do not allow to drop below 30ppm as it will not protect the chlorine from being removed by UV rays.
