Salt Water vs. Chlorine: What’s the Difference?
If you’re in the market for a new pool or considering upgrading your current one, you may be wondering about the differences between a pool with a salt water system and a pool with chlorine. Both options have their pros and cons, and it’s important to understand how they work to keep your pool clean and safe for swimmers. In this article, we’ll explore the key differences between salt water and chlorine pools.
Salt Water Pools
Salt water pools use a salt chlorine generator to produce chlorine naturally from salt. A small amount of salt is added to the water, and then the salt chlorine generator uses a process called electrolysis to break down the salt into hypochlorous acid (HOCl) and sodium hypochlorite (NaOCl), which are both forms of chlorine.
The chlorine produced by the salt water system works to eliminate harmful bacteria and microorganisms in the pool water. The salt chlorine generator produces a consistent amount of chlorine, which means that pool owners don’t have to worry about adding chlorine to the water regularly.
One of the biggest advantages of salt water pools is that they are gentler on the skin and eyes compared to chlorine pools. This is because the levels of chlorine produced by the salt water system are lower compared to traditional chlorine pools. Salt water pools also have lower maintenance requirements as there is no need to add chlorine tablets or granules on a regular basis.
Chlorine Pools
Chlorine pools are more traditional and use chlorine tablets, granules, or liquid to sanitize the pool water. Chlorine is effective at killing harmful bacteria and microorganisms in the pool water, making it safe for swimmers.
Chlorine works by releasing hypochlorous acid and hypochlorite ions into the pool water. These chemicals work to break down organic matter in the water, such as sweat, urine, and algae, which can lead to cloudy water and unpleasant odors.
One of the biggest drawbacks of traditional chlorine pools is that the chlorine levels can fluctuate, which can cause skin and eye irritation. Chlorine pools also require regular maintenance, including adding chlorine to the water, monitoring chlorine levels, and regularly shocking the pool.
Which is Better?
Both salt water and chlorine pools have their advantages and disadvantages. Salt water pools are gentler on the skin and require less maintenance, but they are more expensive to install. Chlorine pools are more traditional and less expensive to install, but they require more maintenance and can be harsh on the skin.
Ultimately, the decision between a salt water pool and a chlorine pool comes down to personal preference and budget. Regardless of which system you choose, it’s important to maintain the appropriate levels of chlorine or salt in the pool water to keep it clean and safe for use. Regular testing and adjustments to pH, alkalinity, and calcium hardness levels can help to keep your pool sparkling clean all season long.
