Choosing Pool Disinfectants: Comparing the Pros and Cons of Chlorine vs. Bromine

Since you are here to read the post, I believe you have understand the essential role disinfectants act in ensuring a clean and safe water of your pool or spa. So when it comes to pool snatizers for pools and spas, chlorine and bromine are the two most commonly used chemicals. They are both chemical compounds that serve a similar function: decontaminate pool and spa water by killing bacteria effectively.

However, you may feel confused, which one is the best choice for you?We present the pros and cons of each so that you can choose the option that’s best for your situation.

Chlorine

Pros

• Effectively kills or inactivates pathogens and algae

• Multiple use options (tablets, granules, liquid, gas, etc.)

• Easier to apply

• Works in indoor and outdoor pools

Cons

• Harder to keep pH balanced

• Strong smell

• Irritating to people with sensitive skin

• Applied more frequently

• Less effective at high temperatures

• May cause eye or skin irritation

Bromine

Pros

• Remains stable at higher temperatures

• Easy to keep pH balanced

• Little smell

• Kills bacteria and viruses effectively

• Gentler on the eyes and sensitive skin

• Added less frequently

Cons

• - Degrade faster when exposed to sunlight

• - Not as effective below 75°F

• - Pool water will be cloudy

• - Harder to rinse off skin

• - More expensive

Chlorine: The Versatile Sanitizer

Effectiveness

Chlorine works well indoors and outdoors, is incredibly effective and well-loved by many pool owners. It works faster to kill contaminants but for a shorter period, for it dissipates faster.

Both chlorine and bromine are susceptible to degradation by the sun UV rays, and bromine dissipates slightly faster. There is no substance that stabilizes bromine to prevent UV degradation, while chlorine can be stabilized by cyanuric acid.This makes bromine a better choice for an indoor pool or spa.

Ease of Use

Chlorine can be applied in three different ways: granules, liquid, or tablets. The granules or liquid can be added directly to the water without any specialized equipment, while the tablets are placed in a floating dispenser to maintain adequate levels of chlorine in the water.

So you can choose the method that works best for your routine, whether it’s using a floating dispenser for tablets or pouring liquid chlorine directly into your pool.

pH Impact

Chlorine woks effectively within a range of pH levels, Keeping pH within 7.4 to 7.6creates the perfect environment for chlorine to act. So keeping track of pH leves to ensure a safe pool environment is important for pool owners.

Odor

Chlorine is known to have a much stronger odor, causing unpleasant swiming experence. Chlorine can be harsh for those with sensitive skin or eyes or those with breathing conditions such as asthma.

Bromine: A Mild Disinfectant

Effectiveness

Bromine works more slowly but provides longer-lasting protection and helps maintain water chemistry more balanced due to its lower pH, meaning less chemical adjustment is needed. Bromine generally requiring a higher amount to achieve the same level of sanitation as chlorine.

Higher Cost

Bromine usually tends to be more costly than chlorine. Generally more bromine will be required than chlorine to achieve the same clean results. Plus, bromine is best dispensed through a floating feeder or cartridge dispenser, which also adds to the initial cost of using bromine.

On the other hand, you tend to use bromine less often than chlorine, so it is possible that the cost of using bromine or chlorine actually equals itself out over time.

Stability

If you have a hot tub or a heated pool indoors, bromine is your go-to guy. Unlike chlorine, bromine remains stable and effective, especially in warm water. This stability makes bromine preferred for indoor spas or heated pools.

Gentle on skin and eyes

Bromine also has a softer side. It tends to be less irritationg on both skin and eyes compared to chlorine. If you or your guests have sensitive skin or eyes, bromine may be a better option, allowing for enjoyable swims without the stinging discomfort often associated with chlorine.

But if someone is allergic to chlorine, bromine is also not a safer alternative because it is still chlorine-based.

Odor

Bromine does not emit the same strong chlorine smell like chlorine, but bromine does leave a lingering smell that is harder to rinse off your skin than chlorine due to its stability.

pH Tolerance

With is its ability to perform well over a broader pH range, Bromine offers consistent sanitation even when the pH levels vary. This quality can be especially beneficial for busy pool owners who may not always have time to monitor water chemistry meticulously.

Usage

Bromine typically comes in tablet or granule forms, requiring a bromide or dispenser for easy and controlled distribution,you may only need to add bromine once a week.

Usually one application bromine can last up to a week, you may just need add it once or week. While chlorine may needs to be added every other day or so as it dissipate soon.

Making the Choice: Bromine vs. Chlorine

Opt for bromine if:

You have an indoor pool, particularly heat.

Swimmers have sensitive skin and eyes.

You’re looking for a sanitizer that tolerates fluctuating pH levels well.

Opt for Chlorine If:

You have an outdoor pool.

Seek an economical solution.

Prefer versatile options and easier usage.

As a whole, the decision between bromine and chlorine usually depends on your personal situation, preferences and the unique layout of your pool. Except for the products themselves, your swimming habits, the type of pool you have (indoor or outdoor) and who will be swimming in it, may be taken into your consideration.

Ultimately, both bromine and chlorine are very effective sanitizers for pools and spas, but understanding their unique characteristics will help you make the right choice.
