This system is
not compatible with bromide chlorination, hydrochloric acid use and/or acidic
pool/spa water (pH less than 7.2)
. Sodium Carbonate must be added to protect the system
from acidic pH (<7). pH should be maintained between 7.2-7.8 for maximum system longevity.
If required Sodium Bisulphate acid can be used to keep the pH down.
For maximum pump and system longevity we strongly recommend a non-chlorine/bromide
based sanitation method.
