Most of the pools that homeowners have nowadays are disinfected using chlorine as the main disinfecting agent, and saltwater pools are no different. Although salt is added to the pool, it’s broken down by the brominator into its two distinct parts: sodium ions and chlorine ions. In the saltwater pool, the chlorine ions are then turned into Hypochlorous acid—an ingredient that disinfects but doesn’t end up irritating the swimmer’s eyes like chlorine can.

Not just any type of salt can be added to a swimming pool, however. Although the salt that’s used in these pools are chemically similar to table salt, they manufactured in a way that makes the conversion process that occurs in the pool a lot smoother. To help our readers convert their current pool to saltwater or keep their saltwater pool in good condition, we’ve listed the ten best pool salts below.

A Guide To Buying & Using Pool Salt

Since so many people are switching to saltwater pools, we thought it might be relevant to talk about how to buy the best pool salt products and how to use them effectively. Regardless of whether you’re going to purchase one of the products from our above list or are looking for some other brand of pool salt, this guide is sure to provide you with all of the information you are going to need. Let’s get started and delve into this subject a little bit further.

How To Buy Pool Salt

Salt products are extremely important to civilization. This product is so important that it comes in a myriad of different forms, from the table salt that we use to season food to the road salt that’s used to treat roads during the winter. However, when it comes to pool salts, the consumer only has three different options available. These three types are Mined Salt, Solar Salt, and Evaporated Salt. Let’s take a closer look at each of these pool salt types to determine which ones are the most effective.

  • Mined Salt – As its name implies, this type of salt is mined from rock salt mines. This type of salt is used for a variety of different applications, but there’s probably no application where it’s more effective than in a swimming pool. That’s because this salt is some of the purest types of salt the pool owner can find, with some brands having an almost 99% composition of Sodium Chloride. That’s why this type of salt is the one that most pool owners prefer. It’s also the type that we recommend the most for saltwater pools.
  • Solar Salt – The next type of salt that’s available is solar salt. What is solar salt, you ask? Well, it’s a salt that’s made by placing ocean water in an open holding bin, where it is then exposed to the sun. When the ocean water evaporates, it leaves behind salt. Solar salt is produced because it’s one of the cheapest ways that manufacturers can produce salt. Unfortunately, the type of salt is not without its drawbacks. One of its main drawbacks is that ocean water just doesn’t contain particles of salt in it, but it also contains microorganisms–microorganisms that die during the evaporation process. That means the when pool owners are adding solar salt to their pool, then they’re not only adding sodium but they’re also adding the carcasses of various microorganisms such as brine shrimp. Because of salts’ inherent nature, bacteria can exist in it, but there are still those microorganisms contaminants to think about. Of course, these contaminants will be filtered out by the pool’s filter. However, why add something that has to be filtered out in the first place? That’s why solar salt is not a preferable type of salt for pool owners.
  • Mechanically Evaporated Salt – Mechanically evaporated salt is made from ocean water that isn’t dried by the sun but is instead dried by mechanical methods. This process kills microorganisms in the salt faster, then solar stills do. This process allows the manufacturer to remove some of the organic contaminants from the water but it doesn’t remove some of the mineral contaminants from the water. These contaminants can include iron, silicates, phosphates, calcium, copper, and nitrates. These contaminants might require the pool owner to have to adjust their pool chemistry more than they would have to if they used a pool salt that uses mined salt.

How To Use Pool Salt

Having just covered what pool owners should look for when shopping for pool salt, we thought that we should now talk about using pool salt effectively. Although the following tips shouldn’t replace the directions of both your swimming pool and your pool salt product, it does contain some information that some pool owners might find useful.

Step One: Read All The Directions

Yes, we understand that we just stated that the pool owner should read the directions of the Salt Chlorine Generator’s Owner’s Manual as well as the pool salt, but we think it’s worth repeating here. Most Salt Chlorine Generators operate with a target range of 3,000-4,000 parts-per-million, but there are exceptions, so definitely read the directions. Once you understand the salt concentration levels required, you can then proceed to step two.

Step Two: Check The Pool’s Salt Level

Once you understand the salt concentration levels required for the pool, it’s time to do some tests. If the pool is brand new, the salt concentration will, of course, be at zero parts-per-million, but if you’ve used the pool before, then you are going to test the water. You are also going to have to test the water if you are converting from a standard chlorinator to a saltwater chlorinator. In those cases, you will usually find that the salt levels are somewhere in the 300 to 550 ppm salt range. Salt testing strips are readily available both online and at pool stores.

Step Three: Determine How Much Salt Is Needed

The next step is to determine how much salt the pool needs. For most systems, the salt range will have to be brought up to 3,500 to 4,000 ppm. To determine how much salt is needed to reach that level, you need to figure out the current saltwater level, and how many gallons of water is in the pool. Then those figures can be plugged into a Salt Water Pool Table (they can be found online or in pool stores) to figure out how much salt is needed. Below we’ve listed some common examples that we’ve taken from Salt Water Pool Tables.

For example, suppose you have a 10,000-gallon pool and your current salt level is 1,500 parts-per-million. In that instance, you would need 167 pounds of salt. On the other hand, if your pool’s salt level is at 0 PPM and you have a 20,000-gallon pool, then you are going to need 584 pounds of salt to be added.

Step Four: Add The Salt To The Pool

Making sure that the Salt Chlorine Generator is turned off, it’s time to add salt to the pool. During this process, the pool’s pump can be left on to circulate the water and speed the process of the salt dissolving, but the generator should remain off until the salt has dissolved completely. Salt shouldn’t be poured into the skimmer but should be poured into the shallow end of the pool. It can take up to 24-hours for the salt to dissolve, so be patient. Once it has dissolved, turn on the salt chlorinator. Now it’s time to check the salt level of the pool. Make sure that the salt level isn’t too low, which can reduce chlorine production, or isn’t too high, which can shorten the life of the cell. If the salt level is in the range recommended by your Salt Chlorine Generator, then your job is done and you can now enjoy your pool.
