What Does Chlorine Do?

Pool owners use this chemical as a means to eliminate their pools of harmful bacteria and other germs. This usually occurs in a two-step process. The chlorine first acts as a disinfectant, killing bacteria or algae. Then, it oxidizes, chemically destroying dirt or other foreign materials found in a pool.

If you’re installing a new pool, our guide on How to Install a Fiberglass Pool Shell explains how proper installation supports long-term water quality and easier maintenance.

How Much Chlorine Should You Use?

On average, a swimming pool contains anywhere from 3 to 5 ppm of chlorine. You can calculate how much chlorine you need to sanitize your pool with a standard measurement. An above ground swimming pool that is 48 inches tall and 15 feet wide contains 4,978 gallons, whereas an in-ground pool can hold 31,000 gallons or more depending on its size. You can also determine the number of gallons your swimming pool can hold by calculating the volume of the pool, then converting that amount into gallons. Since chlorine tablets are the most common form for dispensing chlorine, determine the size of your pool to find the number of tablets needed.

Test the appropriate amount of chlorine by measuring a pool’s pH level. The pH level measures the acidity in the water; this level can affect vital chemical reactions occurring inside the pool during the cleaning process. A normal pH level for a swimming pool ranges between 7.2 to 8.0 pH.

Is Chlorine Harmful?

If it’s misused, chlorine can be very harmful. About 10% of homeowners fail routine pool inspections, so it is imperative that pool owners adhere to using the correct amount of chlorine needed for the size of their pool. Chlorine reacts with other organic materials such as urine, feces, sweat, and saliva all commonly found in a pool. This creates disinfection byproducts also known as chloramines that have a distinct smell. While many consider clean pools to be bright blue in color, it may actually be a sign of an unsanitary pool.

To protect your pool during colder months, consider installing Inground Pool Winter Safety Covers, which help maintain water quality and reduce seasonal damage.

How To Safely Use Chlorine

There is a safety requirement for each of the seasons. Both winterizing your pool and preparing for spring’s pool opening requires the same amount of care as during the summer season.
