Should total chlorine and free chlorine be the same?
Should total chlorine and free chlorine be the same?
Put It All Together. If total and free chlorine levels are the same, there’s no combined chlorine in your water, meaning none of it has been used up yet. In order for your pool to be properly sanitized, the free chlorine level must remain higher than the combined chlorine level.
Why do I have total chlorine but no free chlorine?
Chlorine lock can occur when there is too much cyanuric acid (also referred to as conditioner or stabilizer) in the water. This occurs when too much stabilizer is added to the water or when the swimming pool isn’t being partially drained and refilled periodically. Chlorine lock can also occur if the pH is unbalanced.
What should total and free chlorine be?
For most pools, the chlorine level should remain between 1 to 3 ppm. Chlorine levels lower than 1 ppm place swimmers at grave risk of contamination; never let the chlorine dip below this level. Greater chlorine levels than 3 ppm will continue to kill contaminants but will be an eye and skin irritant.
Can you swim in a pool with high free chlorine?
Pools will naturally gas-off chlorine from the surface, and very high levels can irritate airways and lungs when inhaled for prolonged periods, especially indoor pools. At chlorine levels over 10 ppm, swimsuits can begin to fade, and pool covers become damaged, and it may be unhealthy for swimmers.
Does shock raise free chlorine?
“Shocking” refers to the process of adding chlorine or non-chlorine pool chemicals to the water in order to raise the “free chlorine” level. The goal is to raise this level to a point where contaminants such as algae, chloramines and bacteria are destroyed.
What should free chlorine be in pool?
between 1.0 and 3.0 parts per million
For a healthy pool, the free chlorine level should be between 1.0 and 3.0 parts per million (ppm). The Centers for Disease Prevention and Control recommends pH 7.2–7.8 for pools and hot tubs.
What do I do if my pool has no free chlorine?
How to fix chlorine lock
- Partially drain the pool. Partially draining your pool is probably the best choice since you should be doing it occasionally anyway.
- Non-chlorine shock. Non-chlorine shock oxidizes the water, restoring the balance and making it cleaner.
- Chlorine shock.
Will Shock raise free chlorine?
Free chlorine is just that, free. Free to interact with other chemicals, algae, bacteria or the like. Shocking then releases the combined chlorine and off-gasses the contaminants, increasing the amount of free chlorine in your pool or spa.

Will chlorine tablets raise free chlorine?
Raising pool chlorine can be much easier than trying to lower chlorine levels. Simply adding chlorine in the form of chlorine tablets, granular chlorine, liquid shock or powder shock will increase the total amount of chlorine within the pool.
What does free chlorine mean in pool?
Free Chlorine. Free chlorine is the chlorine that is available to combine with contaminants in the water to disinfect and sanitize the water. Chlorine that is added to swimming pools is “free” chlorine, in that it has not yet bonded with nitrates, ammonia or other compounds in the dirty pool water.
