Saltwater or chlorine in your pool: which is better?

Posted By

Water, if left untreated, will quickly turn green as algae and other organisms are given a chance to reproduce and thrive. This goes for swimming pools too, so to keep it all clear, healthy and ready for use, the water must be treated continuously. The two most common ways of upholding this kind of maintenance are through the use of chlorination and saltwater electrolysis. But like everything, there are pros and cons for each method –  so which is better?


Keeping your pool clean with chlorine


Using chlorine to treat pool water is ultimately a quick process, and the chemicals are relatively cheap and easy to buy. The chemical works by reacting with contaminations, such as organisms and bacteria, and neutralising them. As these reactions occur, they change the balance of the water overall.


Chlorine also breaks down in the sunlight and heat. Because of this, chlorinated pools require a great deal of maintenance to upkeep their ability to clean out contaminants. The down-side of using this process is that the water needs regular checking and the chemical balance requires continuous correction. Additionally, regular pool ‘shocks’ need to be applied to keep all the levels in check.


It’s also a harsh chemical and can irritate the skin, eyes and hair. In some cases, it can also impact your lungs, and the smell is usually not that pleasant to put up with.


Using a salt water chlorine generator to clean pool water


Surprisingly, chlorine is also used in saltwater systems, but the chemical is created continuously by the salt water generator. Because of this, extra chemicals are not needed in most circumstances. As salt does not break down or evaporate in water, it rarely needs topping up, making it a cost-effective approach for those looking to save on dollars.


Beyond that, maintenance is far easier to deal with. The balance of the water is kept level on its own, so checking it is not so much of a priority.


As for health-related benefits, saltwater in a pool is not as strong as the ocean, so it’s far less likely to cause any irritation. In fact, it’s a milder solution and is often kinder to swimsuits too. And you won’t get that potent, annoying smell that you can’t get out of anything.


Although saltwater systems have many benefits, some things make them less attractive. The biggest downside is that these generators are more expensive to install initially. Over many years of pool use, however, the cost of chlorine will add up to become more than the installation of a saltwater system, so it’ll balance out all the same. Another issue that can occur is the staining that can pop up on your pool due to salt deposits – which can be quite prominent on darker coloured designs.


Getting started


Above all, when it comes to choosing the best way to keep your pool clean, you have to consider what matters most to you. Are you looking for cost-effectiveness or something with less upkeep? Or do you find yourself worrying over the pH levels and health impacts related to chlorine water? Ultimately, making the decision will come down to what you’re willing to invest in initially, as well as the time you have on hand to keep up maintenance required. However, for anyone concerned with the health issues raised by chlorine use, we always recommend opting for a saltwater generator.
