Swimming Pool Chemistry 101: Understanding Chlorine Levels and pH Balance

  how to reduce chlorine in pools A crystal-clear swimming pool on a sunny day is a sight to behold, inviting you to take a refreshing dip. However, maintaining that pristine appearance involves more than just regular cleaning and filtration. Swimming pool chemistry plays a crucial role in keeping your pool safe and enjoyable, with two fundamental factors at the forefront: chlorine levels and pH balance. Let us now look into the basics of these essential elements to help you maintain a healthy and inviting swimming pool.

Chlorine: The Pool's Guardian

Chlorine is vital to swimming pool maintenance. This is because it is a powerful disinfectant, effectively killing bacteria, viruses, and algae that can turn your pool into a breeding ground for unwanted microorganisms. This means that chlorine oxidises these contaminants, thereby making them harmless. However, maintaining the right chlorine level is a delicate balancing act. If there is too little chlorine in your pool, it will become a breeding ground for harmful pathogens. This will, in turn, lead to cloudy water and potential health hazards. On the other hand, excessive amounts of chlorine can irritate swimmers' skin and eyes and produce unpleasant chemical odours. In such a case, it is essential for you to learn how to reduce chlorine in pools to maintain optimal levels. To keep chlorine levels in check, you need to conduct regular testing. For this, you can use test strips or a liquid testing kit to measure the chlorine concentration in your pool. The ideal range for free chlorine, which is the active form that disinfects the water, is typically between 1.0 and 3.0 parts per million (ppm). However, it is important to give due consideration to factors that can impact chlorine consumption, such as:
  • Pool usage
  • Weather conditions
  • Water temperature
Maintaining the proper chlorine level is a delicate matter. This is because when chlorine is added to the pool, it combines with contaminants to form chloramines. Chloramines are less effective at disinfection and can lead to a strong smell of chlorine. However, you can easily combat this by shocking your pool periodically. Shocking involves adding a high dose of chlorine to break down chloramines and restore the pool's chlorine balance.

pH Balance: The Unsung Hero

While chlorine takes care of pathogens, pH balance is responsible for maintaining the comfort and safety of swimmers. pH measures the acidity or alkalinity of your pool water, which is crucial for several reasons. A pH level that is too low (acidic) can:
  • Corrode pool equipment
  • Cause skin and eye irritation
  • Weaken the effectiveness of chlorine
Conversely, a high pH level (alkaline) can lead to cloudy water, scaling on pool surfaces, and reduced chlorine efficacy. The ideal pH level for pool water is between 7 and 7.6 on the pH scale, which is slightly above neutral (pH 7). To maintain this balance, you can use pH test strips or a digital pH meter to check your pool's pH level regularly. If it falls outside the recommended range, you can use a pH increaser (sodium carbonate) to raise pH or a pH reducer (sodium bisulfate) to lower it, as needed.

The Balancing Act

Now that we understand the importance of chlorine levels and pH balance, let's discuss how these factors are interconnected. The pH level can impact the effectiveness of chlorine. If the pH is too high, chlorine becomes less active and less effective at disinfection. Conversely, if the pH is too low, chlorine becomes more active and gets used up quickly, leading to inefficiency. Maintaining the right pH level can help optimise your chlorine's performance and reduce the amount of chlorine you need to use. This saves you money and minimises the risk of skin and eye irritation for swimmers. Understanding and managing chlorine levels and pH balance is fundamental to keeping your pool water clean, clear, and comfortable. Regular testing, adjustments, and a good understanding of how these factors interact will ensure your pool remains a source of relaxation and fun all summer.

Pool Heating Maintenance Tips to Keep Your System Running Smoothly

  As a pool owner, one of the key roles in keeping your pool in tip top condition is properly maintaining your pool heating system. A well-maintained pool heater not only ensures that your pool is always at the perfect temperature for swimming, but, if working at maximum efficiency, it can save you money on energy costs and extend the life of your pool heating system. Here are some helpful tips for maintaining your pool heating system and keeping it running smoothly:

Schedule Regular Maintenance

Regular maintenance is key to ensuring your pool heating system continues to operate efficiently. Schedule routine maintenance appointments with a licensed professional to inspect and service your pool equipment, including your heater, at least once per year. During these appointments, a technician will clean the unit, inspect the components, and make any necessary repairs to your heater to keep it in tip-top condition.

Keep the Heater Area Clean

Keeping the area around your pool heater clean and free of debris is essential. Leaves, dirt, and other debris can accumulate around the unit, reducing its efficiency and increasing the likelihood of damage. To prevent this, regularly sweep or blow away any debris in the vicinity of your pool heater.

Check the Water Flow

Another critical step in maintaining your pool heating system is to check the flow rate. Ensure that water passes through the system correctly by checking the pressure gauge on the filter. If the pressure is too high or too low, it could indicate a problem with the filter or pump, which can cause the pool heater to malfunction. If your heater includes a safety flow switch, then the device will automatically switch off to prevent any damage to the heater or overheating of the pool water.

Monitor the Water Chemistry

Proper water chemistry is essential to keeping your pool in good condition and protecting your pool heater and other equipment from corrosion and other damage. Test your pool water regularly to ensure it has the right pH balance and chlorine levels. If your heater is manufactured with stainless steel components, and the water chemistry is off, it can often lead to corrosion, scale buildup, and other issues that can damage your pool heating system. To prevent such damage, look out for pool heaters that use titanium flow tubes and heating elements. Titanium guarantees corrosion-free operation and extends the life of your heating system.

Check for Leaks

Leaks are one of the most common problems with pool equipment, including pool heaters. If you notice any water pooling around the unit, it could be a sign of a leak. Leaks can cause damage to your pool heater and even lead to electrical problems if water gets into the electrical components. If you suspect a leak, switch off the heater from the mains and call a professional right away to have it repaired.

Keep an Eye on the Thermostat

The thermostat is the control center of your pool heating system, and it's essential to keep a close eye on it to ensure that it is working properly. If the temperature reading appears inaccurate, it could indicate a problem with the thermostat. This can cause your pool heater to work harder than it needs to, leading to increased energy costs and potential damage to the system. Many of today’s pool heaters are fitted with a safety overheating sensor to avoid such issues and to prevent overheating of the pool water.

Address Problems Promptly

Finally, addressing any problems with your pool heating system as soon as possible is important. If you notice any issues with the unit, such as strange noises or poor performance, don't wait to have them looked at. Prompt repairs can prevent further damage and save you money in the long run. Proper maintenance is essential to keeping your pool heating system running smoothly. By following these tips and scheduling regular maintenance with a professional, you can enjoy a warm and comfortable pool all year round, while also saving money on energy costs and extending the life of your pool heating system.

Drain the Water and Prevent Frost Damage During the Winters

When winter arrives and you are not using your pool heater, it is important to drain the water from the unit. This will prevent damage due to freezing temperatures. In addition, make sure the area around your pool heater is insulated to help protect against frost damage.

Cover the Pool to Keep the Temperature From Dropping Dramatically

Finally, another great way to maintain your pool temperature is to cover the pool when it’s not in use. This will help keep the water temperature from dropping dramatically, which can then put an extra strain on the heater and cause unnecessary wear and tear.

Keeping Your Hot Tubs And Swimming Pools Safe From Coronavirus

With guidelines and restrictions constantly changing it can be difficult to know what activities are safe and allowed. In this blog, we’ll look at the ways that you can keep your hot tub and swimming pool as safe as possible during this hard time. We’ll also look at the reasons why it is safe to continue using your swimming pool or hot tub during the COVID-19 pandemic.


One of the best resources for getting up to date information on the scientific facts around Coronavirus and what activities are safe is the Centre for Disease Control (CDC). The CDC deals with the safety risks surrounding COVID-19 and they have got this to say about the use of hot tubs and pools:
“There is no evidence that COVID-19 can be spread to humans through the use of pools and hot tubs. Proper operation, maintenance, and disinfection (e.g. with chlorine and bromine) of pools and hot tubs should remove or inactivate the virus that causes COVID-19.”
So, what does this mean? Essentially, as long as you are carrying out a proper maintenance and disinfection routine as part of the operation of your pool or hot tub then you should not have to worry about the spread of Coronavirus while using these facilities.

Ways to keep safe

As mentioned above, proper maintenance and disinfection is a key element in helping to ensure the safe operation of your pool or tub. UV systems and chemical dosing should continue to be used as part of your regular pool maintenance to help kill off any pathogens and bacteria in the water. You should also ensure that people are cleaning their body before entering the pool or hot tub to help keep the water as sanitary as possible. In line with government guidelines you will also need to ensure the following measures are taken:
  • Social distancing Social distancing measures should be put in place to limit the number of people that can use the facilities at any one time. The easiest way to do this is to require people to book a time slot for usage.
  • Temperature checks Temperature checks are a great option to help minimise the risk of people who may potentially have Coronavirus from using your pool or hot tub. In addition to this people should be discouraged from using facilities when they are ill or showing any of the symptoms associated with Coronavirus. While chemicals and cleaning systems should effectively kill the virus in the water there is still a risk of them spreading infection by touching other surfaces and equipment.
  • Cleaning routine Strict cleaning regimes should be implemented to disinfect all hard surfaces and regular microbiological tests should be performed on the water to make sure that it is safe. It is also a good idea to limit the use of shared facilities such as changing rooms to help prevent the spread of the virus.
