The midpoint of 7 is said to be neutral, above which is alka-line and below which is acidic. In spa water, IT IS VERY IMPORTANT TOMAINTAIN A SLIGHTLY ALKALINE CONDITION OF 7.2 to 7.8. Problemsbecome proportionately severe the further outside of this range the watergets. A low pH will be corrosive to metals in the spa equipment. A high pHwill cause minerals to deposit on the interior surface (scaling). In addition, theability of the sanitation agents to keep the spa clean is severely affected asthe pH moves beyond the ideal range.
