How to Increase Bromine in Pool: A Step-by-Step Guide

Swimming is a beloved activity for many, offering both fun and relaxation. However, maintaining a pool’s cleanliness and ensuring its water is free from harmful bacteria is paramount. One of the most trusted sanitizers for pools is bromine. If you find the bromine levels in your pool lacking, you’re in the right place. Dive in with us as we detail the steps on how to increase bromine in pool and discover why it’s essential for an optimal swimming experience.

What is Bromine?

Before diving deep into the methods of increasing bromine in pools, it’s vital to understand what bromine is and its role in pool sanitation.

Bromine is a halogen, much like its close relative, chlorine. Found in various forms, it primarily serves as a sanitizer for pools and hot tubs. When introduced into pool water, bromine reacts with organic materials like bacteria and algae, neutralizing them and rendering the pool safe for swimmers.

One of the unique attributes of bromine is its resistance to high temperatures. Unlike chlorine, which can evaporate swiftly in hot climates, bromine remains stable. This makes it a favorite for many pool owners, especially those with heated pools or those located in warmer regions.

Why is Bromine Favored Over Other Sanitizers?

Bromine’s stability is not its only advantage. It offers several benefits that make it stand out in pool maintenance:

  1. Gentleness on Eyes and Skin: While all sanitizers may cause some degree of irritation, many users find bromine to be gentler than chlorine. This means fewer red eyes and less skin dryness after a swim.
  2. Less Odor: Unlike the strong chlorine smell, bromine tends to have a less potent aroma, making the swimming experience more pleasant for many.
  3. Effective in Various pH Levels: Bromine works efficiently across a more extensive pH range than chlorine. This means even if your pool’s pH level isn’t perfect, bromine can still be effective.

Why is it Important to Maintain the Correct Bromine Level in Your Pool?

When it comes to pool sanitation, balance is crucial. Just as a pool with too little sanitizer can become a breeding ground for bacteria, a pool with too much can cause its own set of problems.

Insufficient Bromine: A bromine level that’s too low is an open invitation to harmful bacteria, algae, and other microorganisms. These unwanted guests not only make the pool look unappealing with their presence, but they also pose health risks. Swimmers in such pools are vulnerable to infections, skin rashes, and even more severe health problems in prolonged exposure scenarios.

Excess Bromine: On the flip side, over-sanitizing your pool with an excessive amount of bromine can cause problems too. High bromine levels can lead to:

  • Skin and eye irritations, making swimming uncomfortable.
  • Potential degradation of pool equipment and accessories.
  • A change in water quality, affecting the overall look and feel of the pool.

In essence, maintaining the correct bromine level is a delicate balancing act. Too little, and your pool becomes a health hazard; too much, and you compromise the swimming experience and potentially damage your pool equipment.

How to Increase Bromine in Pool

Balancing the bromine levels in your pool might seem like a daunting task, but with a bit of knowledge and patience, it can be quite straightforward. Depending on the kind of bromine system you’re using, there are different methods to adjust the bromine levels.

For those using Bromine Tablets:

  1. Testing First: Always begin by using a reliable test kit to measure the bromine concentration in your pool water.
  2. Assessing the Level: If the test reveals that the bromine level is below the optimal range (typically between 2-4 ppm), it’s time to introduce more bromine.
  3. Adding Bromine: Introduce bromine tablets either directly into your pool skimmer or a floating dispenser. It’s important to remember that different pools require different amounts of bromine, so always follow the manufacturer’s recommendations.
  4. Monitoring: After adding the bromine, allow it to circulate in the pool for 24 hours. After this period, retest the pool water. Adjustments might be needed based on these results.

For those with a Bromine Generator:

  1. Initial Testing: Just as with bromine tablets, the first step is to use a test kit to determine the current bromine concentration.
  2. Making Adjustments: If the bromine is below the desired level, you can increase its concentration by adjusting the settings on your bromine generator. Typically, turning up the dial will lead to increased bromine production.
  3. Post-Adjustment Testing: After making adjustments, wait for about 24 hours before testing the water again to ensure it’s within the desired range.

Maintaining Healthy Bromine Levels: Pro Tips

Ensuring a consistently safe and pleasurable swimming experience requires regular maintenance. Here are some tips to help maintain the bromine levels in your pool:

  1. Consistent Testing: Make it a routine to test the bromine levels at least once a week, and even more frequently during peak swimming times or very hot days.
  2. Weather Watch: Bromine consumption can spike during hot days or when the pool sees heavy use. Be ready to add more bromine during these periods.
  3. Shocking the Pool: This process helps eliminate accumulated organic contaminants. Regular shocking can also help improve the doing its job well of bromine in sanitizing the pool.
  4. Maintain Water Balance: Besides bromine, it’s crucial to monitor other parameters, especially pH. Ideally, pool water should have a pH level between 7.2 to 7.8. Proper pH levels ensure that bromine works effectively.
  5. Use Stabilizers: UV rays from the sun can break down bromine, reducing its doing its job well. Consider using a stabilizer to shield bromine from the sun, especially if your pool receives a lot of direct sunlight.


Swimming pools are sources of joy, relaxation, and fitness. To ensure they remain so, it’s crucial to maintain optimal water quality. Bromine, as a powerful sanitizer, plays a pivotal role in this. By understanding its significance, and by following the outlined steps and tips, pool owners can ensure a safe and delightful swimming environment. Whether you’re a newbie to pool maintenance or a seasoned expert, remember that regular testing and adjustments are key to a pristine pool. Dive in with confidence, knowing your pool is clean, safe, and ready for fun!
