2.1 Preparing the pool: water balance

The Zodiac® electrolyser or hydroxinator are designed to disinfect pool water.
With the pH Link module, it automati cally maintains the pH value of your pool.
With the Dual Link module (electrolyser only), it automati cally maintains the pH value and chlorine level (ACL or Redox
potenti al) of your pool.
It is essenti al that the pool water balance is controlled and adjusted before installing the appliance. Making sure that the
pool water balance is correct from the very start will reduce the likelihood of encountering problems on the fi rst days of
operati on or during the season the pool is in use.
Even if it is an automati c control system, it is essenti al to analyse the water regularly to check the water balance
parameters.
