Swimming Pool Water — What Are Your Options

Nobody likes to swim in dirty or algae infested waters. A swimming pool, like any large, still body of water, can quickly become a breeding ground for various organisms and bacteria if you aren’t careful. That’s why taking the right precautions is so important to ensure that you have a clean and healthy swimming pool ready to go whenever you want to use it. 

The chemicals used to clean a swimming pool are great at helping to keep you and your family safe when in the water. Two primary systems are available to help keep your pool balanced with the right chemical mixtures to prevent unwanted growth, while also minimising skin and eye irritation. Both systems have their advantages and disadvantages, so understanding each one and what the benefits are is important before you make your final decision. In this article, we will discuss the most common types of swimming pool water systems—chlorine and salt/mineral water systems—to help you make the best and most informed decision possible. 


Chlorine water pools use large amounts of water-soluble chlorine to prevent bacterial growth. Chlorine is added in either powdered or tablet form and dissolves leaving crystal clear water. Chlorine swimming pools are the most common type of swimming pool you will have experienced, especially when it comes to commercial pools. 

Chlorine pools are a good choice if you want something easy to use and cheap. Their history as the most common pool type means their design has been well refined and supplies are available everywhere at very reasonable costs. Maintaining your chlorinated pool to keep bacteria at a minimum and prevent the growth of unwanted algae and other organisms is as simple as buying and dropping in the chemical regularly. 

The main downside of chlorinated swimming pools is that they can be rough on skin, hair, and eyes. This is especially a concern if you plan to use the pool daily or have sensitive skin. It can also be tricky to properly balance the levels of chlorine in the water without performing regular checks and tests. 

Salt and Mineral Water 

Salt-water pools are a great alternative to traditional chlorinated solutions. Don’t worry, though; they aren’t salty like ocean water. Salt-water pools use a salt-chlorine generator to keep the pool free from unwanted elements. The mild salt-water of the pool enters the generator unit which processes the salt and water into hydrogen and hypochlorous acid. The acid is what replaces the need for traditional chlorination powder. Salt-water pools are a fairly new consumer product, but they are very quickly gaining popularity. 

Salt-water pools are a perfect solution if you want to avoid regular maintenance since their design means they do not require regular top-ups and testing of chlorination solutions. They are also much gentler on hair, skin, and eyes, making them especially good for those with sensitive skin. Salt-water chlorination is also much safer, especially if you have young children, as there is no need to store dangerous chemicals (chlorine) in your home. 

Of course, they do have a few downsides as well. Salt-water systems are more expensive to install and get running than drop-in chlorine. While they are very reliable and generally maintenance-free, if something does go wrong, they will usually require a specialist technician to repair.
