Just shock it to break point and your at free chlorine.

What is the difference between free chlorine and total chlorine?
Combined chlorine is when the chlorine molecule has attached itself to other molecules in water. In other words it has "combined" with something else in the water. Those could be iron, manganese, ammonia or other things depending on the source water. Free chlorine is the molecules that are "free" in the water to do the disinfection.
How do you get the free chlorine level down in your saltwater pool?
To give you an accurate answer, it's important to know how many gallons are in the pool, how high is your Free Available Chlorine (FAC), and what is your Combined Chlorine Reading. Is pool enclosed and protected from sun etc? Is your chlorine generator working properly? You could simply shut down the generator and test your pool everyday at the same time. Keep records of pH, Free Chlorine, Combined Chlorine, Alkalinity, etc. It's important that you maintain a proper pH at ALL TIMES.
How do you get the ideal reading of chlorine in the pool?
When chlorine enters the water, it is in a form that is an active sanitizer and an oxidizer called "free chlorine". It will react with any number of contaminants in the water. When it reacts with ammonia compounds in the water, which come from bathers' perspiration and urine, it becomes "combined chlorine". In this form, chlorine is a much slower sanitizer. This form also causes chlorine odor and eye irritation. When using the 5-way strip, the difference between the free chlorine reading (pad 1) and the total chlorine reading (pad 2) is the combined chlorine reading.
How do you get chlorine free water?
Many people install salt water systems under the impression that it is chlorine free. Salt water systems produce chlorine electronically and therefore does not require adding chlorine to the water physically. So salt water is not chlorine free water. There are alternative pool sanitation systems that use an advanced oxidation process, combined with copper ionization to sanitize the water. These oxygen based systems do not produce any chlorine. These systems produce 100% chlorine free water.
How do you lower the combined chlorine level?
Actually you add more chlorine, I would recommend 12 1/2% liquid. You need to reach the breakthrough superchlorination point to oxidize the contaminants creating the chloramine or combined chlorine. You can also use potassium monopersulfate which is a non-chlorine oxidizer and will allow you to use the pool sooner as it will only free up the chlorine already in the pool. Depending on several factors you may need to add some chlorine after using the PMS.
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.
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.
Chlorine free pool sanitation?
Using an Oxygenation unit combined with Copper and Silver residuals. Three Bands available.

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.

What is total residual chlorine?
Total Residual Chlorine (TRC) is the total of free available residual chlorine and combined (bound) residual chlorine. The amount of measurable chlorine remaining after treating water with chlorine i.e. amount of chlorine left in water after the chlorine demand has been satisfied

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.
