Best Salt Water Chlorinator Buying Guide

There are several factors to consider before investing in a quality saltwater chlorinator. Some of these may just be the make it or break it deal for you.

Therefore, we have compiled a list of all the important factors you should consider prior to investing in a chlorinator. Knowing these things about your product will give you an upper hand when you decide to purchase a chlorinator.

  • Brand

It is a fact that the brand you buy your product from is very important. Buying from a renowned brand which makes quality products is always a better option than buying a gimmicky product from an unknown brand. This would also ensure you end up with the top of the line product always.

Renowned brands such as Haywards, Solaxx have a ton of reviews online which gives you more room for inspection, so you really know everything there is to know about the unit.

  • Pool type

Another essential factor to consider before purchasing a salt water chlorinator is the type of pool you have.

salt water chlorinator buying guide

Some products work well only for in-ground pool whereas some work for above ground pools. So, before investing in a product, it’s important to research it well, so you don’t end up buying a product that doesn’t work for you.

If you end up purchasing the wrong type of chlorinator, it would not work for you and cause you a lot of trouble.

  • Installation

A saltwater chlorinator is not a cheap investment; therefore, you would want it to be as convenient as it can be for you.

The installation process is a very important part of buying a product. You would want a product with an easy installation process so you can do it yourself saving the money you’d pay for professional help. This would make the product more convenient for you and overall provide a better value for you.

  • Size

Chlorinators come in a lot of different sizes. So, prior to investing in a product, you should make sure that it fits the place you’ve chosen for it. Some products might need extra assistance as in plumbing or accessories. Furthermore, some products work online while others work offline.

All of these factors are important to consider before buying a chlorinator. The size, the accessories, and the work procedures should be something you are mindful of.

  • The cell

It is the most important part of a saltwater chlorinator. It is the component which converts salt into salt water chlorine. Therefore, the product should have a long warranty for its cell, so it’s durable and works for a long time without needing any repairs.

  • Control board

The name says it all. It is the brains of the product. It controls the functionality of your saltwater chlorinator. Additionally, it is responsible for providing electricity to the chlorinator, and it will also be the component you use to control the amount of electricity your unit uses.

The control board of the salt water chlorinator allows you to fluctuate the amount of saltwater chlorine in your pool.

How do saltwater pools work?

It is always important to know how the machine you own works. It could help you fix it or install it. We already have mentioned the two most important components of a saltwater chlorinator previously.

One of them is the cell, whereas the other is called the control board of the unit.

The cell is where the process of electrolysis occurs to convert salt into salt water chlorine. Meanwhile, the control board, as the name suggests, is responsible for controlling the process by providing the cell energy.

The control board also allows you to control the levels of electricity given and the amount of salt water chlorine formed. You can increase or decrease both.

Now, how this product works is by a simple chemical phenomenon known as electrolysis, which surely most of you must be familiar with.

Chlorine comes from NaCl, which is more commonly known as salt. The chlorinator cell has the salt water going inside. Meanwhile, the cell has electric plates to which electricity is applied, causing salt to dissociate into chloride ions which convert into chlorine gas.

This gas dissolves into the water, which then comes back into your pool.

Advantages and disadvantages of salt water chlorinator

Like all machines and equipment, saltwater chlorinators also come with their set of advantages and drawbacks.

  • Advantages

We have discussed the maintenance of your saltwater pool in detail. It will make you realize how low maintenance your saltwater pool really is as compared to the benefits it provides. You only need to annually clean the cell and check up on it after 3 months.

Isn’t that great?

Once you’ve installed a salt water chlorinator to your pool, you will no longer need to add chlorine to it. You only need to add salt, which is much cheaper, and salt will be converted to chlorine automatically by the machine through the process of electrolysis.

This way, you will get the necessary chlorine, which keeps the water clean.

The name salt water chlorinator may scare you, but the fact is the salt levels in your water are reduced as chlorine is derived from them. The little amount of salt that does get left behind is not harmful to your skin or your eyes. It will not sting them. Therefore, you need not worry about residual salt.

Store bought chlorine not only stings your eyes but is also damaging to your skin and hair. The chlorine produced by a salt water chlorinator is lesser in quantity and therefore not harsh. It wouldn’t dry your hair out or harm your skin.

In fact, it is great for people with allergies and sensitive skin since the water is mild and gentle, which is certainly not going to cause your skin any problems.

  • Disadvantages

It can be an expensive investment since the units are not too cheap. Thus, your budget should be flexible for this investment, so you are able to buy a good quality product which is durable and works well with your pool.

Not only are the initial costs a lot but also the installation and operating costs of this product are pretty high. Upon investment in such an expensive product, nobody would want to ruin it by handling it themselves if they aren’t well equipped with how to install it.

Hiring professional help to install it costs a lot. Plus, if you end up investing in a model which isn’t electricity efficient, it may cost you a fortune.

This machine requires you to add salt to the water, which may actually cause long term damage to your pool. There will be slight wear tear which will take a long time before it starts becoming noticeable as the salt is present in the tiniest amounts.

Maintaining a Saltwater Pool

You shouldn’t think that once you’ve bought and installed a salt water chlorinator, your job is done. Saltwater pools require maintenance.

Luckily, it’s not very laborious or time-consuming, but it is necessary. Thus, do not forget to take the following measures to keep your saltwater chlorinator functioning perfectly and to maintain your saltwater pool.

salt water chlorinator maintaining

  • Keeping the cell clean

The cell, as we’ve mentioned earlier, is the most important part of your saltwater chlorinator. Therefore, it is crucial to keep it working fine.

The cell of your unit will get dirty over time. Thus, you’re required to clean it to keep it functioning well. However, it isn’t a frequently recurring thing which you’ll have to do. This could be an annual deal.

However, do check the cell after every three months for any calcium build up, which is not good for your chlorinator. Calcium prevents adequate amounts of chlorine to be formed. Therefore, it should be gotten rid of under all circumstances.

  • The alkalinity

Your pool’s alkalinity is an important quality which you need to keep in check. Low alkalinity could result in staining, corrosion, and the formation of algae. Meanwhile, high alkalinity levels could result in your pool being cloudy. So, you need to find a balanced middle spot that works for you.

  • The pH

The pH of your pool is another thing you need to be mindful of. The right pH will allow the chlorine to kill off the germs and bacteria in the water.

Therefore, for the chlorine to be effective, you need to keep your pH maintained. For doing so, you might occasionally need to add acid to your pool, which will help you to get your required pH levels.

  • Checking the chlorine levels

You may think of this as an extra precaution, but it’s more than that. Checking your chlorine levels is very important for your pool overall. If the chlorine levels are quite low, you may need to add more salt.

It could also be evident in calcium build up in your cell, which is inhibiting chlorine formation. As we’ve mentioned earlier, calcium isn’t good for the cell of your saltwater chlorinator as it prevents the conversion of salt to chlorine.

Salt Chlorine generator FAQs

We have answered some of you most asked questions. Take a look!

  1. What exactly is a saltwater pool system?

A saltwater pool system engages the simple phenomenon of electrolysis to produce chlorine gas. This dissolves in water to provide the required chlorine from salt. You install a machine in your pool to do so instead of getting store-bought chlorine.

  1. Is my saltwater pool free of chlorine?

Not really. Instead of adding store-bought chlorine, you add salt which produces chlorine. However, the chlorine produced from the salt is lesser in quantity than your store-bought chlorine. It functions just as well in keeping your pool healthy and clean without being as harsh as the alternative.

  1. Which type of salt should I use?

You do not need any special kind of salt for this process. You can just use normal salt. However, make sure that it is not iodized.

  1. Wouldn’t the salt hurt my eyes and skin?

Quite the contrary, in fact! The amount of salt present in the water is not harmful to your skin in any way. It will not sting your eyes either. The amount is so little that it actually helps in keeping your skin and hair soft.


Hopefully, by now, you will have made a decision as to which product you should invest in. Even though all of the products we talked about are great, there is one product that stood out to us.

It is none other than the Haywards Goldline AQR15! This product is amazing, truly. The brand is largely trusted by millions globally, and this product is a winner. It works efficiently and effectively and makes your pool experience amazing. Overall, it is a great investment.
