How to Lower Chlorine in a Swimming Pool: 5 Natural Methods to Try

You might want to know how to reduce chlorine in a swimming pool if you’ve been a little clunky with your pool sanitizing solution. Of course, a touch of this product is great for getting rid of bugs and bacteria, but as they say, too much of a good thing can be bad.

We are all for the safety of our loved ones, and adding a little disinfectant is a good idea for your backyard paddling pool. But when adding chlorine (aka CI), proceed with caution. It’s always best to read the manufacturer’s instructions and the back of the chlorine solution bottle to know how much to add.

However, if you added too much, you risk harming your family and friends. Generally speaking, it’s a good idea to assess the size of your tub and do a quick math equation to determine the appropriate amount to add.

While we don’t want to scare you, using chlorine in OTT poses many (avoidable) health risks, and saturating pool water can lead to headaches, vomiting and dizziness. Not what you want when splashing around is supposed to be a fun pastime.

Fear not, if you accidentally used a higher concentration than necessary, we’ll find out how to reduce chlorine levels in a swimming pool. Sure, you can buy a store-bought solution, but many of these products sound just as scary as chlorine, not to mention more expensive than the (familiar) natural remedies we have in mind. Either method is also virtually free, as long as the weather is on your side. So without further ado, let’s dive into…

Why you might want to reduce chlorine in a swimming pool

The experts at Arm & Hammer (opens in a new tab) saying that “most people know that chlorine is an important chemical for keeping pool water safe for swimming”,

“But adding too much chlorine can lower your pool’s pH as well as its total alkalinity. When alkalinity drops, it’s harder to maintain a stable pH. Additionally, lower pool water pH and alkalinity will your pool create several negative effects, from itchy skin and itchy eyes for swimmers to corrosion of your pool ladders, liner or other pool furniture.

“When the alkalinity of your water is too low, any chemicals you add will exponentially affect the pH, creating a condition known as pH bounce. You’ll also need to add more chlorine to get the same sanitizing effect, and your swimmers will complain about that. Overall, pool water with inadequate alkalinity levels can be frustrating and costly.

1. Stop adding chlorine

OK – who invited Captain Obvious to the pool party? If you’ve sanitized your kiddie pool enough with chlorine, the last thing you’ll want to do is add even more solid stuff to their paddling pool. After all, children’s skin is sensitive, and too much of this chemical element can cause skin problems, as well as itchy eyes and even respiratory problems.

“For chlorine readings slightly above the recommended chlorine concentration, reducing chlorine levels in your pool can be as simple as not adding chlorine to your pool,” says Michael Hoffman, president of Backyard & Pool Superstore. (opens in a new tab)

‘Turn off your chlorine dispenser, remove the chlorine floater from the pool or remove the chlorine tablets from the skimmer. Reducing the continuous influx of chlorine into your pool allows the chlorine currently in the pool to be used. Swimming in the pool can help speed up this process because the chlorine works to eliminate bacteria introduced by swimmers.

The same is true if you tried to fix a green pool and shocked it by adding an excessive amount of chlorine. Lower the chlorine and step back.

2. Bring sunshine to your pool

Want to know how to reduce chlorine levels and clean a swimming pool for free? Just add sunshine. The burning ball of gas in the sky is literally a cleaning star. And it all depends on those all-important UV rays, as Hoffman explains.

He says, “A quick and easy way to dissipate chlorine in your pool is to enjoy a warm, sunny day. UV rays react with free chlorine to create chlorine gas, which is released into the atmosphere.

“To try this method, stop chlorinating your pool and continue to monitor chlorine levels to make sure they don’t drop below 2 ppm. Once they reach that level, resume regular chlorination to sanitize your pool. swimming pool.

And Gregory McFarland, Head of Product Offering, Pool Knight (opens in a new tab) says: “Just two hours of sunlight on a nice day can reduce the chlorine level in your pool by up to 90%.

3. Heat your pool water

If you’re hot and bothered and thinking about ways to reduce chlorine in a swimming pool, this tip to increase the temperature might just be the heat-related hack you need in your life.

This clever process can also be used in a hot tub to reduce the volume of sanitizer before it ends up bleaching your favorite swimwear. You can either turn up the heat if you have a super sleek hot tub with sleek features, or add a few boiling water kettles to a basic pool.

“Temperature can indirectly affect chlorine levels in pool water. An increase in temperature causes the proliferation of bacteria, which consume more chlorine. said Hoffman.

“If you have a heated pool, consider raising the pool water temperature to 90°F – 10°F above the recommended level – for a short time. Continue to monitor chlorine levels throughout the day.

McFarland adds, “High temperatures also indirectly break down chlorine. Since most bacteria grow more easily in warm water, when there are increased numbers of bacteria in the pool water, more free chlorine becomes combined chlorine. Basically, the chlorine is exhausted.

4. Dilute the pool with more (non-chlorinated) water

Just like when you pour yourself a refreshing glass of cordial, adding more water to the container can help weaken the strength of pool bleach. Use your garden hose to fill your H2O with cold water and test the pH with your test strips (available on Amazon) (opens in a new tab).

The recommended range for a pool’s total alkalinity is between 80 and 120 parts per million, so if you’re using this specific product, you’re looking for a medium green to teal hue. Anything outside of that palette and you’ll need to take action.

‘To dilute your pool water, partially drain the pool and then refill it with fresh water. However, this method has several disadvantages compared to other chlorine reduction tips,” warns Hoffman.

“Emptying and refilling your pool takes a lot of time. Reduce the time it takes to drain the pool by backwashing if you have sand or DE filters. Pool water dilution can also significantly increase your water bills, depending on the municipal water rates in your area.

“It also upsets the pH level and hardness of your pool water, which you will need to monitor and readjust carefully after you have finished diluting the pool. This method can be a good option for pool owners who also have to deal with a clogged sand filter, increased total dissolved solids level, or excess copper or cyanuric acid.

5. Increase pool alkalinity with baking soda

If you are an avid reader of real houses items, you’ll know that cleaning with baking soda is fast, cheap, natural, and just plain magical. So instead of using a commercial cleaning product, why not opt ​​for baking soda? (opens in a new tab)to lower the concentration of your chlorine?

“Don’t waste money on commercial alkalinity-raising pool products when you can use baking soda to raise your pool’s pH and alkalinity instead,” advises Arm & Hammer.

“As with sanitizer levels, be sure to check the pH daily. Each time the pH drops below 7.2, add 3 to 4 lbs. of baking soda per 10,000 gallons of water to raise pH. If after about a day the pH has not stabilized and drops back below 7.2, add another 4 pounds of baking soda per 10,000 gallons of water. This procedure should bring the alkalinity back to the desirable ppm range and stabilize the pH between 7.4 and 7.8 for several weeks.

On the contrary, Alicia Johnson, business owner, Cleaning Green LLC (opens in a new tab) explains that while baking soda works to counter chlorine issues, it doesn’t work the way we think it does.

She says, “Contrary to popular belief, baking soda does not directly lower a pool’s chlorine levels, but aids in the chlorine neutralization process. One of the highly alkaline chemicals is baking soda and adding it to your pool will raise the pH and alkalinity of the water.

“So why do people confuse it with something that helps with chlorine? Easy. People also use hydrogen peroxide to reduce chlorine levels in their pool water. But it only works effectively if the pH level of the water is high enough. So you raise the pH and alkalinity of the water using baking soda, then use nitrous oxide to bring it down to a safe level.

What is used to lower chlorine levels?

“There is a popular product line that goes by the name of commercial chlorine neutralizers.” says Johnson.

“These are quick and inexpensive ways to reduce chlorine levels in your pool water. Sodium thiosulfate is one of them and is widely used to neutralize chlorine in water so the family can swim The best part is that it is completely safe to use and has no drawbacks or side effects, plus it is very cheap and easily accessible.
