Just shock it to break point and your at free 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.
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.
Available chlorine refers to the active chlorine present in a disinfectant or bleach that is capable of performing the desired sanitizing or oxidizing functions. It includes both free chlorine (hypochlorous acid and hypochlorite ion) and combined chlorine (chloramines) in a water solution. Available chlorine levels are crucial in ensuring effective water treatment and sanitation processes.
If you have too much combined chlorine in your pool, it can lead to eye and skin irritation, as well as create an unpleasant smell. To reduce combined chlorine levels, you can shock your pool with a chlorine shock treatment, which will break down the combined chlorine compounds and free up the chlorine to sanitize the water effectively. Regularly maintaining proper chlorine levels and practicing good pool hygiene can help prevent the buildup of combined chlorine.
If your total chlorine is high and your free chlorine is low, it means that the chlorine in the water is mostly bound to contaminants and is not available to sanitize the pool effectively. This situation could result from the chlorine being overused or ineffective due to high levels of organic matter. To correct it, you may need to shock the pool to break down the combined chlorine and restore the free chlorine levels.
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.
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.

Using an Oxygenation unit combined with Copper and Silver residuals. Three Bands available.
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.

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

Available chlorine levels are crucial in ensuring effective water treatment and sanitation processes.
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.
