best pool salt water chlorinator systems It is difficult to make up your mind considering that you have so many options to choose from – even when it comes to sanitizing your pool. But perhaps getting acquainted with the main pros and cons associated with salt water chlorinator systems is a good starting point. Here are some upsides.

  • They don’t require a lot of maintenance

This, indeed, can sound very appealing. When your spare time is limited and you want to make the best use of it, a salt water chlorinator system is a godsend. Distinct from chlorinated pools, this type of system sanitizes your pool so that you can use it freely without your personal involvement.

Does this sound appealing to you? If the answer is positive, perhaps it’s time you invest in such a unit. Instead of adding sanitizers to your pool to ensure that it’s safe for swimming, you’ll only have to conduct regular tests. These tests are usually related to the pH, alkalinity or the hardness of the water.

In addition to that, note that, typically, salt incorporates a range of sanitizers. This actually reduces the growth of algae. Therefore, it will necessitate less cleaning.

  • They are free from harsh chemicals

While it is true that a saltwater pool will still contain chlorine, you won’t have to include other sanitizing chemicals. In addition to that, you won’t have to worry about your pool emitting a strong chlorine odor that is utterly unpleasant.

On top of that, according to a 2003 study, young children who swim on a regular basis in a chlorinated pool feature a higher risk of developing asthma or lung inflammation.

  • More comfortable for swimmers

Considering that the chlorine levels inside the pool will be quite low, this will positively impact the comfort of the swimmers. Therefore, common symptoms such as irritated skin, red eyes, discolored hair should no longer be an issue. That has to do with the fact that saltwater is naturally healthier and softer.

Usually, the irritation that occurs after swimming in a pool occurs due to the high levels of chlorine inside the water. On that note, people with allergies or suffering from asthma might be able to swim in a pool sanitized with such a system.

  • Versatility

What Are the Drawbacks of Pool Salt Water Chlorinator Systems?

Each product on the marketplace usually comes with a bunch of pros and cons. It’s up for each customer to assert them and determine whether he/she is willing to make compromises in that area or not. To that end, salt water chlorinator systems make no exception. Here are some drawbacks you should think about.

  • It requires an upfront investment

Over the course of time, it might make sense to invest in a salt water chlorinator system. Still, initially, it entails an upfront investment. This could be inconvenient for some people.

  • It’s not all you need

Types of Pool Salt Water Chlorinator Systems

Types of Salt Water Chlorinator SystemsIt is interesting to point out that salt water chlorine systems have been introduced in the second half of the 20th century. As you might expect, the very first units were big, bulky and noisy. Nowadays, the salt water chlorination systems we can choose from are entirely different, also in terms of efficiency and size.

The system comprises of two key parts. One of them is the control panel, which features the user interface functionality of the system and the electronics. This is basically what differentiates distinct types of salt water chlorination systems: the way in which the control panel is designed and organized.

Some of the simpler types of units will come with an on/off button, a shock/turbo button and output up/down button. On the other hand, the types of systems that could be characterized as high end allow you to control the pump. You might also choose to set up a timer, and the list could go on.

The second part of the system would be the cell. Basically, the cell comprises of three to seven blades of titanium. These blades of titanium feature a thin layer of iridium or ruthenium.

As an alternative to a salt water chlorination system, you might also consider investing in a top-notch pool water test kit. Another alternative might be getting chlorine tablets for pools. Evidently, each option might appear to be more convenient for some people, but there’s no such thing as a one-size-fits-all for every user.

You can always look up for more information about pool supplies and accessories by browsing online. Considering that there are so many options to choose from, it’s always a good idea to look for a supplier of pool accessories. And the Internet is a good place to start.

  • Standard vs. Self-Cleaning Systems

Basically, standard models necessitate the removal of the cells on a monthly basis. This is critical in order to dissolve calcium buildup. On the other hand, self-cleaning models come with a special feature, being capable of reversing their polarity. This way, they prevent calcium buildup.

  • Built-in pH Control Chlorinator System

There are also salt water chlorination systems that feature built-in pH control. Such a device is also meant to regulate the pH level, to ensure that it is healthy for the swimmers.

  • Power Backup Timer Chlorinator

Another category of chlorinator comprises of models that feature backup timers. These timers basically store a lot of important settings, in the event of a power blackout.

Thanks to this unique characteristic, you will know whether the water flows normally or not. In the event of a problem, such a system automatically switches off the pump.

Features to Look for

Stumbling across the best salt water chlorinator by chance is not possible. You have to do some research beforehand and know what to look for in your device. Otherwise, you might not be satisfied with your purchase.

  • Reliability

This is the most important characteristic in a salt water chlorination system. Why is that? Basically, you want to invest in a unit that will stand the test of time.

Reliability is especially important considering that it will function in salty conditions, so to speak. Therefore, it has to be sturdy and well-made, so that it can withstand functioning in tough conditions as well.

  • The reputation of the manufacturer

The reputation of the brand from where you intend to purchase your unit is also important. It’s no secret that each brand has its own values and principles. This is why it’s important to always shop from brands that are known as reliable.

In this way, you can be sure that you’ll get a high-quality product that provides a good price-quality ratio.

  • Low maintenance

As pointed out above, one of the main advantages of investing in a salt water chlorination system is that it doesn’t require a lot of maintenance. And this is obviously a good thing.

You should definitely consider this prior to choosing a specific model. Even if these units are usually made to function effortlessly without a lot of maintenance, some are easier to use than others. It’s only fair.

  • State-of-the-art technology

The use of state-of-the-art technology will evidently impact the longevity of your device. In addition to that, the way in which it is designed matters just as much.

  • Auto-clean function

The truth is that maintaining your pool is a strenuous job by itself. This is why it would be nice if you wouldn’t have to worry about extra maintenance tasks. As we’ve mentioned before, some units have an auto-clean function, which definitely comes in handy.

The auto-clean function refers to the reverse polarity function, which essentially reverses the polarity in order to clean the cell accordingly. The best part is that you don’t even have to press a button or anything for this function.

Maintenance Tips: How to Maintain a Pool Salt Water Chlorinator Systems

It is critical to maintain your salt water chlorinator system adequately. In this way, you will significantly prolong its lifespan, making your financial investment worthwhile. Here are some key tips worth mentioning:

  • Make sure you keep the salt levels between 2700 – 3900 parts per million.
  • Depending on the recommendations of the manufacturer, you should clean the cells of the unit annually, at the very least. But make sure you check the instructions’ manual for more specific advice that applies to your unit.
  • When the weather is stormy, you should switch off the chlorinator. This will reduce the risk of a power surge that will imminently affect the unit.
  • It’s also important to maintain the calcium levels inside the pool as low as possible.
  • If you want to diminish the likelihood of calcium buildup in the cell, you shouldn’t invest in a standard chlorinator.
  • If you want to decrease scale buildup on the cell, you should utilize a salt chlorinator equipped with a reverse polarity feature.

Other Differences

When it comes to chlorine salt generators, you can choose from three types of salt – namely solar salt, mined salt and mechanically evaporated salt.

  • Solar salt originates from seawater, and it is evaporated by the sun. This is why it is prone to have impurities such as bacteria or brine shrimp. This could impair the functioning of the salt generator, negatively affecting the salt water filter.
  • Meanwhile, mechanically evaporated salt derives from sea water. It might also incorporate elements that could damage the pool, but not as many.
  • On the other hand, mined salt is seen as the purest form of salt, since it is obtained by digging from the ground.

Safety Tips

pool salt water chlorinator system reviewsWhen a unit is well-maintained, this means you’ll be able to use it for many years to come. Normally, such a device can be used from three to seven years. When the time comes to replace the board or the cell, then you might spend up to $1,000, depending on the model of your unit and the part that requires replacement.

The truth is that incorrect cleaning, or even too frequent cleaning might cause issues. Due to these issues, you might have to replace a part of the device sooner than expected.

Since the circuit board is similar to any other electronic device, it is prone to get burnt. Although in some cases it might last for years without any complications whatsoever, you cannot be 100 percent certain. A key safety tip is to properly cover the electronic device when the weather is bad, more specifically during electrical storms. This is your best practice against possible early outages.
