My pH is hard to maintain. Why?

Everything that enters your spa has a pH that can raise or lower your pool or spa’s total pH. Check the following:

• Tap water, depending on the area of the country, can either have a low or high pH.
• Overestimating the amount of pH Decreaser or pH Increaser needed is often the problem.
• Using Bromine or Trichlor tends to lower pH over time while using shocks like Calcium Hypochlorite or Lithium Hypochlorite may raise the pH over time.
• High bather loads will tend to lower pH.
• Swimmer wastes, such as perspiration, urine, saliva and other body oils will lower pH.
• A high alkalinity reading will raise the pH.
• Dirt, debris or leaves that blow into the pool as well as rain that is often acidic will lower pH.
• Salt chlorine generators will raise the pH over time.
