Can you over chlorinate a pool?

Risks of Over-Chlorination. While slightly higher-than-normal levels of chlorine in your pool are harmless, exposure to an over-chlorinated pool can have adverse effects on your health and well-being. Excess chlorine can alter the pH level of the water in the pool, making it more acidic.

How do you know if your pool is over chlorinated?

Is a chlorine level of 10 safe?

Pools will naturally gas-off chlorine from the surface, and very high levels can irritate airways and lungs. This is especially true for indoor pools. At chlorine levels over 10 ppm, swimsuits can begin to fade. Pool covers become damaged, and the water is generally uncomfortable and unsafe for swimmers.

How long does it take chlorine levels to go down?

Does chlorine increase pH?

What is the highest chlorine level safe to swim in?

CDC recommends pH 7.2–7.8 and a free chlorine concentration of at least 1 ppm in pools and at least 3 ppm in hot tubs/spas.

If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
