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

Total Chlorine = Free Chlorine + Combined Chlorine
or, put another way
Total Chlorine - Free Chlorine = Combined Chlorine
Free 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 = 1.5ppm
Free Chlorine = 1.0ppm
So, the Combined Chlorine (the difference between the two tests) is .5ppm
Breakpoint 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 chemical do you add when free chlorine is low?
Chlorine
Why is pool Ph low and chlorine high though you have not put chlorine in for weeks?
Do you have a chlorine generator? No.
Why do low temperatures and high pressures required to liquefy chlorine gas?
Chlorine molecules have weak intermolecular forces of attraction.
Does chlorine have a high melting point low boiling point etc?
low melting point, it is a gas at room temperature....
Ph is low and chlorine is high?
Add sodium bicarb to raise pH. Chlorine will go down by itself or add sodium thiosulfate
What if your total chlorine is high and your free chlorine is low?
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 chemical do you add when free chlorine is low?
Chlorine
Why is pool Ph low and chlorine high though you have not put chlorine in for weeks?
Do you have a chlorine generator? No.
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.
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
Does chlorine have a high electron affinity or a low ionization energy?
It has High electron affinity.
Does chlorine have a high boiling point?
No. Chlorine has a very low boiling point considering that it is a gas at room temperature.
Why do low temperatures and high pressures required to liquefy chlorine gas?
Chlorine molecules have weak intermolecular forces of attraction.
What happens when you add chlorine to saltwater?
Sea water contains a low concentration of bromide ion which is oxidised to free bromine Br2 by chlorine.
Does chlorine have a high melting point low boiling point etc?
low melting point, it is a gas at room temperature....
Ph is low and chlorine is high?
Add sodium bicarb to raise pH. Chlorine will go down by itself or add sodium thiosulfate
