Is it bad if pool pH is high?
One of the most frequent problems is when a pool’s pH gets too high. When water is too alkaline, it reduces the effectiveness of the chlorine — the pool chemical that kills pathogens. Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.
Will Shocking a pool lower pH?
Does pH go up after shocking pool? Chlorine based pool shock (Calcium Hypochlorite) has a high pH, and will naturally raise the pH level of your swimming pool water, in addition to changing your chlorine level. Chlorine free shock has a neutral pH, and will not affect any of your pool chemical levels.
What causes the pH level to go up in a swimming pool?
Cause and effect of too high a pH level. An increase in the pH level can be caused by several things. A first cause is the addition of chlorine stabiliser or HTH Granular to the pool water. These strong chlorine products are the best disinfectants but they also result in a direct increase in the pH level.
What should the alkalinity of pool water be?
In other words, if the total alkalinity of the pool water is in the proper range of 80 to 120 ppm, the pH of the pool water will stabilize and be much easier to manage. But if the total alkalinity is below the lowest recommended level, the pH will tend to follow and drop to undesirable levels.
How long does it take to get pool pH back to normal?
Wait about an hour and then test your pH and alkalinity again. If they’re back in balance, then your job is done. But if they’re still off, you’ll have to repeat the process, adding as much soda ash as you need in order to get it in normal range. The water will be a little cloudy, but it should clear within a few hours or so.
How many pH points do I need to raise my pool?
It takes about 6 ounces for every .2 pH points you need to raise 10,000 gallons of water. For example, let’s say the pH in your pool measured 7.0 and you have a 20,000 gallon pool.

How does the alkalinity of a pool affect disinfection?
Your pool water pH and alkalinity can affect disinfection by chlorine. Chlorine is very slow to react at high pH levels, and can be over 50% inactive at pH levels over 8.2. However, even with high pH a pool could still be sanitary with good levels of free chlorine, and clear water from effective filtration.
Is it safe to swim in pool with high alkalinity?
For pools with high alkalinity and high pH levels, add pH Decreaser or other acid, to affect both. Is it Safe to Swim in High or Low pH or Alkalinity? Maybe yes, maybe no. Your pool water pH and alkalinity can affect disinfection by chlorine. Chlorine is very slow to react at high pH levels, and can be over 50% inactive at pH levels over 8.2.
How can I increase the alkalinity in my Pool?
To raise pH and Alkalinity at the same time, start with Alkalinity, and add enough Increaser to raise Alkalinity to 100 ppm. Add 1 lb Alkalinity Increaser per 10,000 gals, to raise Alkalinity 10 ppm. The pool pH level may rise and follow, without added pH Increaser. Pool pH will not Increase (or Decrease)
