When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7.2 to 7.8 – according to the Langelier Saturation Index, or 7.8 to 8.2 – according to the Hamilton Index; higher pH drastically reduces the sanitizing power of the chlorine due to reduced oxidation-reduction potential (ORP), while lower ...
Percent active chlorine is a unit of concentration used for hypochlorite-based bleaches. One gram of a 100% active chlorine bleach has the quantitative bleaching capacity as one gram of free chlorine. The term "active chlorine" is used because most commercial bleaches also contain chlorine in the form of chloride ions, which have no bleaching ...

CT Values are an important part of calculating disinfectant dosage for the chlorination of drinking water.A CT value is the product of the concentration of a disinfectant (e.g. free chlorine) and the contact time with the water being disinfected.
You can even test the chlorine and pH levels yourself before you get in. Pool test strips are available at most hardware and pool supply stores, or for free from the Water Quality and Health ...
This bacterium is one of the leading causes of skin infections in the world. Such infections could appear as painful boils and rashes. [2] It is naturally present in humans on skin, in nasal mucous, and inside the intestinal tract. [3] S. aureus has a strong resistance to chlorine, which is one of the methods by which pools are often cleaned. [4]
