What Is Free Chlorine In A Swimming Pool. Most kits measure free chlorine, but to measure the combined chlorine you need to measure total chlorine. Essentially, free chlorine is in charge of killing bacteria and microorganisms that can potentially make you sick.
Free chlorine is the amount of chlorine freely available to kill bacteria and other contaminates. Free chlorine is the chlorine that is available to combine with contaminants in the water to disinfect and sanitize the water. Use a free chlorine test kit to determine the amount of free chlorine in the pool.
Maintaining the chlorine level in that range depends on several factors, including the ph of the water (it should be between 7.2 and 7.8), and the presence of unwanted substances in the pool, such as urine, perspiration, body oils and lotions, which compete with chlorine and react with it.
These are the good parts of chlorine that are active and able to change chemically to sanitize your pool. Pool managers strive to keep the “free chlorine” level of pool water between about one and three parts per million. Total chlorine is the sum of free and combined chlorine. Free chlorine is an important factor in sanitizing your pool because it’s referring to the amount of chlorine available to fight contaminants in the water.
