Many pool owners get confused as soon as they find out that they actually have to add salt to their pools so that they can keep the pool water in good condition. We are used to the understanding that pool water is fresh and it should not be salty at all.

Salt is actually needed to keep chlorinated pools safe. Some experts say that the salt levels in your pool needs to be at least 2,500 up to 4,000 parts per million. However, you should not be alarmed about it because the human tongue cannot actually taste salt unless it is in quantities of 5,000 ppm.

Salt can also be used to keep the pool more refreshing. It can help make swimmers be more relaxed and help diminish the smell of chlorine. If you have a chlorine generator, you don’t have to keep on putting salt in the water. You just have to put the right amount once a year or after a full drain.

Why Should I Add Salt?

Basically, you need to add salt if you are not using chlorine directly to keep the pool clean. Pool owners who are using chlorine generators are typically the ones that have to add salt to their swimming pools. This is simply because when salt is added to the water, it will naturally form its own disinfectant.

Salt will act on the hydrogen and oxygen found in the water to make hypochlorous acid. This is actually the same chemical that you are making whenever you add chlorine to the water. Although you are not buying, adding or handling chlorine, you are actually disinfecting water the exact same way.

This makes it very convenient for people who do not want to handle or those who hate the smell of chlorine. What’s more, in order to generate adequate amounts of chlorine to keep the pool clean, you will only need to use a set amount of salt per year, making it very safe for different pool equipment.

If you have a chlorine generator system, you should try to use food grade salt, brine blocks or water softener pellets instead of rock salt. This is because most rock salt contains a lot of impurities. What is also great about using salt is that unlike chlorine, if you add too much, you will only have salty water.

So you will know how much salt to use, you have to check the user’s manual of your chlorine generator. There are generators that work at either the 3,000 or 4,000 ppm levels and the manual will help guide you so you will know exactly how much salt to use without damaging the unit.

You should then try to check the level of salt that is currently in your pool. For those who have new pools, you will most likely get a 0 ppm up to a 500 ppm reading. You should find out how many gallons of water the pool holds and then check the table provided by the manufacturer.

In most cases, you will need to use as much as 50 pounds of salt to 2,000 gallons of water so you can make a salt level of 4,000 ppm. With that in mind, you will have to divide the total gallons of water in the pool by 2,000 and then multiply it by 50 pounds so you will know exactly how much salt to use.

If you want to have 3,500 ppm of salt in a 9,690 gallon pool, you will have to use as much as 130 kilograms or 286.6 pounds of salt. For a 12,633 gallon pool, you will have to use 170 kilograms or 374.7 pounds of salt. You can also use online calculators to get the accurate measurements.



If you hate using chlorine because it can easily irritate your skin or nose, I highly recommend that you use a chlorine generator for your pool. With the help of this equipment, you can replace chlorine with salt yet still get all of the benefits that chlorine is known to provide.

You can easily keep your pool clean and you will also be able to remove contaminants. This is because through the generator, the salt can be processed into hypochlorous acid. What’s more, since you are using salt, you will not have to store or regularly handle something as strong as chlorine.

You can also maintain the pool easily. This is because unused hypochlorous acid will be turned back into salt and vice versa. This means that you will only have to top off the salt in the pool once or twice a year if the salt levels get too low from constant water splashing or filter backwashing.
