2-3ppm; 4ppm max.

The pool design is not relevant here: it's disinfectant concentration that matters.

How do you calculate chloramines?

Chloramines can be calculated by the formula: Chloramines = Total Chlorine - Free Chlorine. Total chlorine is the sum of free chlorine and combined chlorine (chloramines). By subtracting the free chlorine level from the total chlorine level, you can determine the amount of chloramines present in the water.


What procedure is used to determine the level of combined chlorine in water?

The level of combined chlorine in water is typically determined using a test kit that measures the total chlorine and free chlorine levels. By subtracting the free chlorine level from the total chlorine level, the level of combined chlorine can be calculated. This measurement is important in determining the effectiveness of water treatment processes.


What to do if total chlorine level is at 3 and free chlorine level is at 10?

If your total chlorine level is higher than your free chlorine level, it is likely due to the presence of combined chlorine (chloramines). This can cause issues with water sanitation and clarity. To address this, you may need to shock your pool with a superchlorination treatment to break down the chloramines and bring the free chlorine level back into balance. Be sure to follow manufacturer instructions and test the water again after treatment.


What do you do if your free chlorine level is 0?

If your free chlorine level is 0, it means that there is no sanitizer in the pool which can lead to bacteria growth. Add chlorine shock to the pool to raise the free chlorine level to the appropriate range for your pool size. It's important to regularly test and maintain chlorine levels to ensure a safe swimming environment.


Can you go in a pool if the free chlorine is low?

Yes, but you should shock it so the water stays clear (do not go in after shocking until the chlorine is at a safe level 1-3ppm)


Can you swim in pool hat has a normal chlorine level but the free chlorine level is high?

There is 3 measurements of chlorine in a pool or spa. Total chlorine, combined chlorine, and free available chlorine. Free available chlorine is the good chlorine that is active in the pool killings germs and algae. Combined chlorine is chlorine is basically chlorine that was once active but has killed germs or bacteria and is now inactive in the pool. Total chlorine is free available and combined chlorine added together. If your combined chlorine is higher than free available chlorine then the water needs to be shocked to eliminate the combined chlorine. But be careful here. If you don't reach what's called break point you will only add to the combined chlorine. There are products on the market which will only remove combined chlorine without effecting your free available chlorine if you are unsure about reaching breakpoint. Hope this helps.


Should you shock the pool if your chlorine level is high?

You only need to shock the pool if there is visible algae, or if the ppm of total chlorine is higher than the ppm of free chlorine. Generally, a level of 2-4 ppm chlorine is all you need to keep your pool sanitary. Let the level drop to that on its own, or use sodium thiosulfate to drop it quickly if you notice itchy skin from excessive chlorine.


What is free chlorine in a pool?

Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.


What do you need to do if your free chlorine level is higher than your total chlorine level?

Get a new test kit or new test reagents. Total Chlorine is the measure of free and combined chlorine, therefore the free chlorine cannot be higher than the Total Chlorine. You can't put 10 gallons of water in a 5 gallon bucket.


What does Cl level refer to When testing pool water?

The Cl level refers to the amount of free chlorine in pool water. It is a critical parameter that needs to be monitored regularly to ensure the pool water is safe for swimming by effectively killing bacteria and other harmful contaminants. Maintaining the proper Cl level helps prevent algae growth, cloudy water, and the spread of waterborne illnesses.


How do you get high free chlorine to match total chlorine?

Total Chlorine = Free Chlorine + Combined Chlorineor, put another wayTotal Chlorine - Free Chlorine = Combined ChlorineFree Chlorine is the chlorine that is doing its job.Combined Chlorine is the chlorine that has combined with contaminants such as nitrogen. It is ineffective as a sanitizer and it is noxious.Total Chlorine is the total of these two levels.To eliminate the Combined Chlorine (making all the chlorine in the pool Free Chlorine) you must shock the pool to remove the contaminants. You must reach "Breakpoint Chlorination", which is the addition of chlorine to your pool equivalent to the Combined Chlorine level times 10.example:Total Chlorine = 1.5ppmFree Chlorine = 1.0ppmSo, the Combined Chlorine (the difference between the two tests) is .5ppmBreakpoint chlorination, in this example would be .5ppm X 10 = 5ppm. So, in this example, you would add enough chlorine to your pool to raise the chlorine level up by 5 parts per million.


How long will it take a chlorine level to drop from 10 ppm to 3 ppm in a 7000 gal pool?

A few days. You will probably be able to use the pool when the level gets to about 5.0 ppm 1) you should know the difference between residual chlorine and Free chlorine 2) Chlorine lost depend on size of you pool and temperature 3) circulation of water , temperature & size of pool will increase chlorine lost
