What is a Saltwater Pool?

A saltwater pool is not very different than other swimming pools, they just use salt instead of chlorine tablets. They do not have any chlorine is a misconception, as saltwater pools use a salt chlorine converter to convert the salt into chlorine.

Adding salt to the water, which is then turned into chlorine, makes the water much silkier, and the salty taste is almost negligible and enjoyable, if there is any.

Many people think that salt water will taste and feel like ocean water, which is not the case; it has one-tenth of salt in the swimming pool compared to the ocean.

How a Saltwater Pool Works?

Saltwater pool works through a salt chlorine generator which converts the salt in the water into sodium chloride with chemical formulae of NaCl.

Let us look at the working process of saltwater pools.

1. The Working Process

The Working Process

The first step towards a saltwater pool is installing a salt chlorine generator in your pool. And then add salt into the pool. Adding your salt to the shallow parts of the pool is highly advised.

Let the pump work for a day, and it will fully dissolve the salt. The pump will have a salt cell, creating a process called electrolysis. This process separates sodium and chlorine. Yes, salt has chlorine, and the pool uses it to stay sanitized.

Instead of using chlorine in added forms, saltwater pools use pure chlorine extracted from salt. Salt in your pool will be nowhere compared to the ocean as your pool’s salinity level will be significantly less, and people won’t even feel the presence of salt in the pool.

The most significant advantage of this saltwater pool is it is almost free from chloramines, a chlorine byproduct that causes roughness of skin and eye irritation, making the water very soft and of the utmost quality.

The process keeps on going, and the system provides chlorine effectively every day in such amounts that the pool remains free from infections, algae, or any unwanted substances.

This system also helps in cost control, it does not need any new amount of salt as the chlorine and sodium extracted from the salt reform in the water after some time, and then the salt cell again works to start electrolysis.

So you don’t have to replace the salt; it starts recycling on its own, making it very cheaper and your maintenance of the pool easy.

How Much Salt Does my Pool Need?

How Much Salt Does my Pool Need?

To decide how much salt you need for your pool depends on the size of the pool. Generally, the manufacturers of the salt system recommend the initial salt level of the pool to be 2400 to 3200 ppm (parts per million) per 10,000 gallons of water in the pool.

Always check your system, as the required range of salt may vary from system to system.

If your salt level is around 3200 ppm, your salt water generator will start working and producing the needed chlorine. This amount of salt is 1/10th of what the ocean has, so it’s almost negligible to feel.

Pool-grade salt comes in 40-pound bags, and if you have a pool size of 10,000 gallons of water, then 6 or 7 bags of pool salt will be enough to make the salt level go from 0 to 2400 – 3200 ppm.

Saltwater Pools For Health

Saltwater Pools For Health

Saltwater pools are generally healthy and do not have any significant known health risks, and are known to prevent skin roughness and eye irritation, which is caused in other chlorine pools.

Saltwater pools are safer for people with breathing problems like asthma or chemical allergies. High chemical smells in chlorine pools are generally a result of chloramines, a formation of chlorine, and ammonia.

This smell can cause severe breathing problems in people who are allergic to chemicals and suffer from asthma.

Saltwater pools are different and do not have any chloramines in them, which makes them a healthy choice.
