      2023’s chlorine shortage forced many owners to look for alternative pool sanitation methods. Saltwater popped up as one of our favorite chemical replacements. Saltwater chlorine generators, or SWGs, are pool gadgets that use salt to make chlorine. They add a small amount of continuous chlorine, reducing maintenance and creating softer, less-chemical pool water.

      Being a more ecological alternative, saltwater pools attract a lot of attention. The main question is which is safer to swim in – pools with SWGs or chlorine tablets?

      In this article, we’ll dive into the main differences between the two and compare their functionality, safety, costs, and other factors.

      Chlorine and Saltwater Solutions Compared

      Chlorine tablets are one of the most popular pool maintenance methods for a reason. They are a simple set-and-forget option and are especially effective for smaller pools. However, there are many scenarios where these tablets don’t work. Saltwater generators pose a convenient alternative, covering most of chlorine’s shortcomings.

      Sanitization and Effectiveness

      Chlorine tablets are very convenient as they provide a constant dose of chlorine. This makes them more effective against bacteria and algae. A saltwater chlorinator, on the other hand, creates a continuous low-level chlorine supply over time. This makes it less effective for tackling heavy bather loads or sudden algae blooms.

      In terms of pure sanitization effect, chlorine tablets can deliver a higher chlorine concentration for a faster kill. They are preferred for heavily used pools or sudden problems that need to be tackled immediately, like bacteria. 

      Safety 

      The big downsides of chlorine are the strong odor and certain irritations it can cause to the skin. This is especially evident in kids with gentler skin or ones prone to allergies. Compared to saltwater, chlorine is considered ‘stringier’. Whereas SWGs are generally softer to the skin and don’t have that unpleasant smell associated with public pools. They are also gentler to the eyes, with a generally softer feel to the water. Of course, the salt system still produces chlorine, so some people may still experience irritation.

      Costs

      Tracking the cost difference between the two systems is complex, contingent upon the pool size and how long you plan on using it.

      This is mainly because chlorine tablets have a lower upfront cost than installing the SWGs pump. But they come with more costs later on as you need to buy more and more of them. While saltwater chlorinators do have a higher upfront installation price, the costs flat out with time. The only thing they require is adding salt, which can be bought in bulk and is much cheaper than chlorine.

      Maintenance

      When it comes to pool maintenance, there is little difference between chlorine and saltwater. Both require you to measure the pH, chlorine, and alkalinity levels regularly. While chlorine tablets are known for sudden pH increases, SWGs are not that self-sustainable either. Whichever care method you use, keep track of your pool situation constantly.

      Verdict

      Both chlorine tablets and saltwater generators have pros and cons. The two have varying costs and effectiveness, and it all depends on your specific needs, pool size, and the time you have to invest in your backyard swimming basin.
