Question 8 How do I help prevent impedance increase at the Spa Boy Electrode?
Maintain the pH level within the target range 7.2 pH – 7.6 pH.
As salt systems naturally drive pH levels upwards, it is most critical to the performance/life of the salt system to
maintain the pH within the target range.
High pH reduces the effectiveness of chlorine.
• pH level of 7 makes chlorine 70% effective (30% loss of effectiveness).
• pH level of 8 makes chlorine 21% effective (79% loss of effectiveness).
Therefore, high pH causes your Spa Boy system to produce more chlorine unnecessarily thus increasing pH even higher and
reducing the effectiveness of chlorine even further.
Strive to achieve a Low pH level 7.2. pH must not exceed 7.6.
Question 9 Why is my water bright yellow, or bright green, or a rusty colour suddenly?
This can happen if the pH gets too high.
Maintain the pH level within the target range 7.2 pH – 7.6 pH.
Lower the pH using ‘Salt Water Balance’. If the colour of the water does not normalize you may need to replace the water.
If pH readings are 8.2ppm or above, a pH error will be displayed on the Top Side Controller every five seconds until the pH is
corrected.
* Keep an eye on the pH and adjust it weekly to avoid this problem in the future.
