Is a pH of 7 OK for pool?
A pH level of 7 means that water is neutral; above 7 means the water is alkaline, while below 7 indicates acidity. Aim for a pH level of between 7 and 7.6. If the water pH is higher than 8, anyone who swims in the pool is at risk of skin rashes, while a pH of lower than 7 can sting swimmers’ eyes.
Is 7.2 pH good for a pool?
Most pool experts recommend a pool pH between 7.2 and 7.8. To raise or lower pH, a pool custodian simply adds acids or alkalis into the water. For example, adding sodium carbonate (soda ash) or sodium bicarbonate (baking soda) will generally raise the pH, and adding muriatic acid or sodium bisulfate will lower the pH.
What is the ideal pH level in a pool?
As pH falls below 7.0 the acidic condition will cause irritation to the eyes and mucous membranes of swimmers. Low pH (acidic water) can also corrode metal parts of a pool system and damage the plaster finish. The State standard for pH is 7.2-8.0 (Recommended range 7.4-7.6).
Is 7.8 pH too high for pool?
Proper pool pH is right in the middle — pool pros recommend that pH be between 7.3 and 7.6 for optimum performance and cleanest water. If the pH gets higher than 7.8, the water is becoming too alkaline. Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.
Why is a pH of 7 considered neutral?
pH is a measure of the amount of Hydrogen ions (H+) in a solution. Ions are just atoms that have an electric charge on them, so H+ is a hydrogen atom with charge of 1. The amount of H+ that is made in pure water is about equal to a pH of 7. That’s why 7 is neutral.
Which has a pH over 7?
Pure water has a neutral pH of 7. pH values lower than 7 are acidic, and pH values higher than 7 are alkaline (basic).
Why does my pool have a purple pH test?
A purple swimming pool pH test indicates that chlorine levels in the pool may need to be lowered. To prevent purple swimming pool pH test results in the future, you should always try to maintain your pool’s chlorine within recommended ranges.
When do I test the pH levels in my Pool?
After neutralizing the chlorine in a pool pH test sample and after determining pool pH, you should always test your pool’s chlorine levels. A purple swimming pool pH test indicates that chlorine levels in the pool may need to be lowered.
What should the total alkalinity of my Pool be?
Total Alkalinity: Total Alkalinity and pH are closely related. A low total alkalinity may cause fluctuations in your water’s pH and exacerbate low pH. Having highly alkaline water can cause pH to drift upwards. Maintain Total Alkalinity between 80—150 ppm.
What should the pH be in a salt water pool?
More than a few people who use salt water pool equipment to generate chlorine safely keep their pH around 7.6 to 7.8. If you are going to shock to high levels, it is better to get the pH down to 7.2 before adding the chlorine. Adding bleach or chlorinating liquid will raise the pH and at shock levels it does so quite a bit.

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.
