Saltwater Vs. Chlorine: Which Is Best For You?

It’s summer, and that means time for swimming, sun, and fun! Along with planning vacations and getting some much-needed rest, many families will also be considering adding a pool to their backyard. Once they decide to install a pool, the next decision is which filtration style to go with: saltwater or chlorine systems. Everyone has a preferred type, but is one better than the other? Let’s go over that today and find out which pool option is best for you, saltwater or chlorine.

How does a saltwater pool work?

First, we want to briefly cover saltwater systems, which the Pool Works Pools & Spas team manages for many customers across our region. These use plates and a process called electrolysis to convert salt to chlorine. The system’s chlorinator dynamically monitors your need and makes the conversion on demand.

This means that, yes technically there is still chlorine in a saltwater pool. It’s simply a matter of how each style of pool uses it and the process that affects the chemical composition.

Saltwater pros and cons

So if both use chlorine anyway, why would a homeowner choose to go with a saltwater pool? First, they’re better for people with sensitive skin as there are fewer chemicals present in the water. Additionally, this lack of added chemicals also means a lack of the distinct odor of chlorine. The average cost of maintaining a saltwater pool compared to chlorine is also less as all you need to buy is salt.

However, there are some negatives to keep in mind. Saltwater is more damaging to your pool lining. Beyond that, the chlorinator is yet another mechanical piece to keep track of — plus it requires occasional cleaning and inspection. In addition, you will still need to test the salt levels and add more as needed. And lastly, the chlorinator will not work when temperatures drop below 60ºF.

How does a chlorine pool work?

Now, let’s talk about chlorine systems. These use various chemicals to maintain your water’s clarity and pH balance. Because of this, the pool water needs to be tested and balanced regularly. This helps to ensure levels are where they need to be to keep the water clean without harming you or your loved ones’ skin.

Chlorine pros and cons

Chlorine pools are synonymous with summer. The smell can instantly transport you to countless childhood memories. Generally speaking, it’s cheaper in the short term to keep your pool as-is rather than undertaking a saltwater system conversion.

On the negative side, chlorine is a hazardous chemical. It must be stored properly and added to the water safely. Additional chemicals are also needed to ensure water sanitation levels are within the necessary pH range. Testing these levels can sometimes be a daily job. Finally, high levels of chlorine can cause skin and eye irritation, faded swimsuits, and more.

Converting an existing pool to saltwater

If you already have a chlorine pool, can it be converted to saltwater? The simple answer is yes. Keep in mind that there are somewhat significant costs involved in switching over.

However, many homeowners find that the lower long-term costs of caring for a saltwater pool compared to chlorine will balance this out.
