Should Total Chlorine And Free Chlorine Be The Same?

What is the difference between free chlorine and chloride?

Most Chlorine is commercially produced and is most widely known for being used within compounds to purify water and create cleaning products.

Chloride: The negatively charged ionic form of Chlorine.

Chloride is what is created when Chlorine gains an electron and combines with other elements..

Does chlorine attack stainless steel?

Chlorine is very aggressive to stainless steels. … Much higher concentrations can be used for short periods as the attack on the stainless steel must initiate and form a stable pit for failure to occur.

Will bleach raise free chlorine?

To raise the free chlorine by 1 ppm, I add about 40 ounces of an 8.3 percent bleach solution, which is about a third of a jug of bleach. You can scale up and down accordingly; if you need to raise the free chlorine by 2 ppm you would add about 80 ounces. … You should add the chlorine just after the sun sets.

What do you do if chlorine is higher than total chlorine?

If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.

What is the free chlorine level in a pool?

Ideal Levels of Free Chlorine, Combined Chlorine, and Total Chlorine. The Association of Pool and Spa Professionals recommends free chlorine levels be kept between 2.0 and 4.0 ppm. The Center for Disease Control recommends free chlorine stay above 1 ppm in pools and 3 ppm in hot tubs.

Is free chlorine dangerous?

Free chlorine is “good” chlorine: it’s still available to kill germs. Combined chlorine is chlorine that’s “combined” with an oxidised organic matter. When the combined chlorine level gets much above 0.2ppm it’s time to get rid of it.

Can I add shock and chlorine at the same time?

Yes, you can add both shock and chlorine to a pool. However, you should not add them at the same time. The best thing to do is to shock your pool first. Then, once the chlorine levels go down to a certain threshold, you can add more chlorine.

Is high free chlorine bad?

Exposure to high levels of chlorine can cause lung irritation, skin and eye damage, and provoke asthma. Not only is it bad for your health, but it can be bad for your pool due to the increase in chlorine. High chlorine levels decrease the pH of your pool’s water, making it more acidic.

Does low chlorine make pool cloudy?

The first and most common cause of cloudy water is low free chlorine levels. Low free chlorine indicates you have chloramine (combined chlorine) that turns water cloudy, smells more of chlorine, and cannot sanitize your pool water by killing harmful germs and bacteria causing algae and ammonia.

Does shock raise chlorine levels?

What is a Pool Shock? “Shocking” refers to the process of adding chlorine or non-chlorine chemicals to your pool in order to raise the “free chlorine” level. The goal is to raise it to a point where contaminants such as algae, chloramines and bacteria are destroyed.

Why is there no free chlorine in my pool?

If you test your pool water and can’t get a chlorine reading, it may be due to your pool’s high demand for chlorine. A high chlorine demand (sometimes referred as chlorine lock), simply means that although your water may appear clear and balanced, the chlorine in your pool is ineffective.

Is 10 ppm chlorine dangerous?

Anything between 5-10 ppm is still safe to swim, but you are risking damage to equipment and certainly complaints from swimmers. Some experts recommend no swimming unless the chlorine is 8 ppm or less. You need to make sure your water is first balanced before expecting an effective sanitizing program using chlorine.

What happens if free chlorine is low?

When the chlorine level is too low, microorganisms like bacteria are able to multiply faster. With harmful bacteria like e-coli, this will quickly cause your pool to be unhealthy, risking any swimmers potentially getting sick. Algae growth. Algae will also grow quickly.

How do I raise the free chlorine in my pool?

Raise the Level of Pool Chlorine Raising pool chlorine can be much easier than trying to lower chlorine levels. Simply adding chlorine in the form of chlorine tablets, granular chlorine, liquid shock or powder shock will increase the total amount of chlorine within the pool.

Why is my total chlorine higher than my free chlorine?

If the total chlorine level is higher than the free chlorine level, the difference of the two is the combined chlorine level. In order for your pool to be properly sanitized, the free chlorine level must remain higher than the combined chlorine level. This is why it’s so important to test your pool water regularly.
