You need to shock the pool. The difference between Total Chlorine and Free Chlorine is tied up and it will be cleared by shocking. Thatis the purpose of shocking.

What do you do when your total chlorine is high and your free chlorine is low?

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.


Cloudy pool free chlorine is not reading stabilizer is low but pH is ok?

Add chlorine and stabilizer.


What if both total and free are very low add shock or tablets?

Yes, add both before the pool turns green. Make sure that you are using a liquid test kit, because the strips always show chlorine as too low unless it is too high. Hatawa


What chemical do you add when free chlorine is low?

You can add chlorine-based chemicals such as chlorine granules or liquid chlorine to increase free chlorine levels in the pool. Follow the manufacturer's instructions and allow time for the chemical to circulate before testing the water again.


What if both your free chlorine and total chlorine is low?

Add more chlorine. More to it than that. Test & if necessary correct the pH first - that's important. Calculate correct dose rate of chlorine & add accordingly. If it's an outdoor pool switch to stabilised chlorine if not already using it.


Does chlorine have a high melting point low boiling point etc?

Chlorine has a low melting point of -100.98°C and a low boiling point of -34.6°C.


Does chlorine have a high boiling point?

No. Chlorine has a very low boiling point considering that it is a gas at room temperature.


Does chlorine have a high electron affinity or a low ionization energy?

Chlorine has a high electron affinity due to its tendency to gain an electron to achieve a stable electron configuration. It also has a relatively low ionization energy, meaning it takes less energy to remove an electron from a chlorine atom compared to other elements.


The bonds in NaCl form because?

Because sodium has a low electronegativity and chlorine has a high electronegativity; sodium become a cation and chlorine an anion.


Low free chlorine?

Try a water conditioner, designed to help your water hold on to chlorine longer. Sometimes a non-chlorine shock can help condition the water to help stabilize your chlorine levels. Could be high heat, phosphates, nitirites, nitrates, or aggressive water. If it's cloudy, a little green, a serious dose of shock may be enough to stabilize it.


Why is the free chlorine level so low even after running the chlorine generator continuously for days?

Could be your PH is not in balance making it seem there is no chlorine, Your salt lavel needs be between 2700 and 3200 ppm. Your Alkalinity may be too far off the scale. Your hardness may be to high and lastly you may have to many phosphates in the water that are consuming the chlorine.


Is chlorine odorless?

No. It smells like bleach, in high levels it can be extremely harmful to the respiratory tract and in high concentrations fatal.
