What should pool pH be to use pool acid?
At a higher pool water pH of 8.0-8.2 and above, the chlorine effectiveness drops to 25%. By keeping your level between 7.8-8.2 or higher, you’re actually wasting almost 75% of your chlorine!! On the flip side, at 7.0, you’ll use too much pool acid, but the chlorine is a bit more effective.
Is it safe to swim with a pH of 8.0?
Starting sixty years ago, pool industry chemists (incorrectly) suggested that a pH of 8.0 and higher makes chlorine ineffective and not safe to swim in. But the truth is that just 1 ppm of chlorine in pool water with a pH of 8.5 and zero CYA contains more active chlorine (HOCl) than needed to kill algae.
Why does the pH in my pool go up when I add salt?
As you can see, chlorine effectiveness decreases dramatically as the pH in water increases. This study tells us two things: The first is that salt generators will cause the pH in a pool to rise quickly. The second is that once-a-week testing and adjustment is not enough to maintain proper pH levels.
How does the pH of the pool affect the effectiveness of chlorine?
The pH in a pool or spa impacts the sanitizer efficacy of chlorine tremendously. For example, at a pH of 7.2, chlorine is 65 percent effective; at 7.8, 32 percent effective; and at 8.0, 20 percent. As you can see, chlorine effectiveness decreases dramatically as the pH in water increases.
What should the pH level be in a salt pool?
Some rise in the pH is normal in a salt pool, but an uncontrollable pH rise is a clue that your salt cell may be running way too long and may result in a severely shortened life span. Your stabilizer level should be 80 – 100 ppm on a salt pool.

What should I do if my pool pH is too high?
If the levels are too high, you will need to lower your water’s pH. A high pH level means your water is too alkaline. You need to use a mild acid to balance it out. Make sure your water sample is from the center of pool, at least 1.5 feet deep. Avoid the skimmer and pool jets. The moving water will distort your sample.
