How Do Salt Water Pools Work?

There’s an incorrect assumption that floats around when it comes to the idea of saltwater pools: the assumption is that there is no chlorine in saltwater pools. This is incorrect, but it’s understandable why some can come to this conclusion.

Saltwater pools are known to be less harsh on the eyes, skin, etc. and this could be the driving factor in the idea that saltwater pools lack chlorine.

We’re here to tell you that there is no lack of chlorine, it’s just not as harsh or abundant. All pools need some form of chlorine to remain swimmer safe. In this case, sodium chloride (NaCl – table salt) is the cleaning agent that is used in saltwater pools.

This salt undergoes a process called electrolysis by which a cell or generator breaks down the sodium chloride, converting it to working chlorine in your pool water.

After the salt enters the electrolysis cell/generator with the dirty pool water and goes through the conversion process, it is pumped back into the pool as chlorine-filled water. The chlorine does its part in decontaminating the pool and when it has reached a certain point, it will convert back to sodium chloride.

At this point, the dirty water containing used chlorine (now reverted back to sodium chloride) enters the cell/generator again, where the process is repeated. This creates an endless cycle of salt to chlorine to salt, back to chlorine, and so forth.

Salt Water Pool System Advantages & Disadvantages

There are both advantages and disadvantages to using a saltwater pool system to chlorinate your pool. Depending on your needs, you may find that either the advantages or disadvantages outweigh one another.

First, here are the advantages:

Gentler pool water:

Because of the reduced abundance of chlorine present in your pool, saltwater systems create gentler water that doesn’t irritate eyes or skin nearly to the extent that chlorine pools do, if they irritate you at all. The reduced chlorine levels also reduce the nasty odors often associated with pools and swimming.

Safety factor:

Saltwater pools are considered by some research to be the safer option for a pool. For one, chemicals like chlorine do not have to be handled and stored. Additionally, research indicates that frequent exposure to heavily chlorinated pools can pose long-term issues and risks.

Automated chlorination:

In comparison to traditional, chlorinated pools, saltwater systems only create chlorine as needed, and therefore require less hands-on maintenance. It also creates less variability in your water’s chemical balance, which is another aspect tied to your pool’s safety.

Smoother water:

Saltwater chlorinating systems are known to create smooth, silky water in your pool. Many people prefer the way the water can almost feel soft in comparison to traditionally chlorinated water.

Less maintenance:

While the pool itself doesn’t require less maintenance, saltwater systems typically remove a good portion of that maintenance from the hands of the pool owner. This results in less time maintaining the water and more time enjoying it.

The disadvantages are:

Initial cost:

For new pools, saltwater systems are typically heavier on the pocket than normally chlorinated pools, requiring a larger initial investment. (it should be noted that the initial cost justifies itself over time as less later investment and upkeep is required for saltwater pools)

Salt systems are complex:

Saltwater chlorination systems are complex and can require the help of a professional technician should a problem arise.

Salt is damaging:

Don’t read too far into this one. However, salt can be damaging to certain materials. This means that with a saltwater pool, you have to be more cognizant of the fixtures and parts you buy for your pool, from filter parts to underwater lights.

Maintenance Tips for Salt Water Chlorinator

Clean scale build-up:

Scale tends to form on the salt cell’s plates at first. It can remain there undetected until a problem arises. Of course, you want to avoid the problem so properly cleaning the scale from the cell plates periodically is highly recommended.

Excessive scale build-up that goes unattended can sharply decrease the lifespan of a salt cell. (In models with reverse polarity, self-cleaning will aid in preventing scale build-up in the cell unit)

Seasonal cleaning:

You should clean the cell once a season as a general rule of thumb. Be sure not to over-clean it when you do.

Salt levels:

Maintaining salt levels is important for preventing excessive scale build-up as well as maintaining proper pool chemistry. You want to shoot to have your salt levels around 2700-3900 ppm.

Turn off during storms:

To prevent damage to the control box and other electro-components of a saltwater chlorinator, you should shut it down when there are storms, specifically during lightning storms. While unlikely that it strikes, it’s an added preventative measure you can take to protect your saltwater system.

Test your pool water:

While it’s not direct maintenance to the saltwater unit, testing your pool’s pH levels, for example, can help you to determine which settings to run your saltwater chlorinator on. By properly balancing your unit’s output you can prevent chemical imbalances in the water that can contribute to issues such as scale.

Replace bad cells:

If by chance your saltwater system cell or generator becomes damaged or inefficient, you should replace it as soon as you can. There is no sense in trying to clean and bring back to life a cell that’s no longer efficiently doing its job. Replacing a bad, or old, cell will ensure your pool gets back to proper functioning.

Tips on Choosing

Do some research:

In addition to these reviews we’ve provided for you, you should do some research on saltwater systems. If you’re still not sure how the process of electrolysis works, look into it further.

No pool system purchase can be successful without a full understanding of the functionality and operation of the process occurring in the unit.

Once you’ve gained an understanding, begin to compare the products by their specs, similar to what we’ve done here. Comparing individual products with one another is the best way to ensure you’re getting value.

Ask around:

If you’re seriously contemplating getting or making the switch to a saltwater chlorinator system, you should ask others how they feel about theirs.

Getting the honest opinion of consumers is a phenomenal way to gauge a product. If you don’t know anyone personally who owns or has knowledge of saltwater pools, you can surely find an online community.

Don’t be afraid to ask all the questions you have, because remember – there are no dumb questions.

Seek professional advice:

Sometimes we like to remain independent and figure things out on our own. Well, for pools, it never hurts to get an expert opinion. Asking a certified professional about saltwater systems and how you could implement one into your pool could be the easiest way to get some answers.

While the DIY options are far and wide, it would be beneficial to know which DIY model you should pursue in your pool and why. A professional can help you figure all of these things out and more.

Be open-minded:

Saltwater chlorinator systems are complex and some aspects of them can seem confusing or straight-up foreign to some of us. The key here is to remain open-minded and not to be scared off by a product over something you don’t understand. Like the research tip, take your time to acquaint yourself with the terminology and specifications of the models.

Factors To Consider

Type of pool:

The type of pool you have carries weight when it comes to the saltwater system you choose to buy. Certain saltwater systems are designed specifically for above-ground pools while others are designed specifically for in-ground pools.

Even still, some models are able to be utilized by either in-ground or above-ground pools. Whether or not your pool is in or above ground is not the only part of the equation, though.

Pool size is a very important factor because salt system generators and cells can only operate up to specific gallon capacities, after which point they become ineffective.

Do you have a filter?:

Another factor to consider when buying a saltwater system is whether or not you already have a functioning filter pump or not.

There are saltwater filter pump systems available for those who are building new pools or those needing to replace old filters.

If your filter pump is functioning great and you simply wish it could be a salt water system, there are options like the salt cells available that are able to be retrofitted onto most filter pump brands and models.

Affordability:

The price of a saltwater system can be a contributing factor as well. As with many products, there are both expensive and generally inexpensive models available for switching your pool’s chlorination to a saltwater system.

Keep in mind, that you do get what you pay for, and while some models are expensive, they are likely to last the longest and work the most efficiently, paying for themselves over time.

Functionality:

The type of saltwater system you desire is a factor to consider when buying a system too. As we’ve seen in these reviews, there are full filter pump sets that utilize sands to clean pool water as well as models that utilize electrolysis to create clean water.

The electrolysis method is a highly efficient way to achieve clean, saltwater pools. However, sand filters do awesome jobs too, and are more than viable for above-ground pools.

Power source:

A final factor to consider is the power source of saltwater units. Some of the models available simply line in with pre-existing power supplies.

Other units require new electrical connections, and while they can be done by the owner, they may require additional help. And lastly, there are the units that have plug-in power sources, many of which need to be waterproofed at the source.

Conclusion

In conclusion, the best saltwater system is the one that best fits your specific needs. Your pool may not be suitable for some of the models on the market, and that will only make your purchasing process simpler.

That’s why knowing what you need and what you are capable of doing is paramount to the searching and purchasing process. We’ve created these saltwater chlorinator reviews in the hope that the researching and buying process has been made simpler or easier for you.

Saltwater chlorinators are ideal for lessening the harshness of your pool and creating silky smooth water the whole family can enjoy! Not only is the water more enjoyable, but saltwater systems also remove a handful of maintenance duties from the owner, making owning a pool less burdensome.

The swimming season is just about here, so there’s no time to delay. Get your saltwater pool system today to kick off an unforgettable season of swimming.
