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.

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

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.


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 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 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.


IS chlorine a good conductor of heat and electricity?

Chlorine is a poor conductor of both heat and electricity. It is a nonmetal with low electrical conductivity and thermal conductivity due to its atomic structure and lack of free-moving electrons.


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 chlorine be liquified?

Yes, at higher pressure and/or low temperature chlorine is a liquid.


Why cl gas and NaCl solid?

Chlorine is an atom. Sodium is a metal, a solid. When Na (sodium) and Cl (Chlorine) react, electrons are exchanged, and the properties of the compound NaCl are different from both sodium and Chlorine. And Chlorine gas is just a state of matter, if in a low enough temperature, it will freeze, becoming a solid. Like


How can you fix low chlorine?

To fix low chlorine levels in a pool, you can add chlorine shock or chlorine tablets according to the manufacturer's instructions. You can also run the pool pump longer to help circulate the chlorine throughout the water. Additionally, you should regularly test the chlorine levels and adjust as needed to maintain proper water sanitation.


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.


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.
