Maintaining the right chemical composition of pool water is essential to keeping the environment safe and clean for swimmers, and it also saves time and money for pool owners. With the steps below, you can get your pool water serviced with the same efficiency as hiring a professional at the same expense.
Steps
Using cyanuric acid
- Some new research shows that CYA really needs to be maintained at a maximum of 40 ppm for chlorine to function optimally (high levels of CYA increase the total amount of dissolved solids that this dissolved solid “does”. decrease” chlorine activity).

Adding chlorine to the pool
Maintain the pH of the pool water
- Usually you will see a high pH and the best way to lower it is to slowly pour “muriatic acid” (also called hydrochloric acid) directly into the deep bottom of the pool while the pump is running and the water is circulating. However, granular acid (a pH reducer) is safer to use than muriatic acid.

Summary of weekly swimming pool maintenance work
- The pH paper will tell you what to do next.
Advice
- Always adjust the chemicals in lake water in the following order: alkalinity, bromine or chlorine levels, followed by pH.
- The difference between chlorine and bromine is that after chlorine combines with bacteria or harmful organic matter, most of the chlorine is used up and no longer has a disinfecting effect on the pool. This “chlorine combination product” will be suppressed in the subsequent shock and the water purifier will remove it. When bromine combines with bacteria in water, bromine remains active but has combined with bacteria and organic matter to neutralize these harmful substances. When you shock a brominated pool, the shock chemical will only destroy the harmful substances but leave the beneficial bromine component in the pool water. The remaining bromine will continue to disinfect the pool. As a result, the amount of bromine pellets needed to disinfect the pool will be significantly less than the amount of chlorine tablets needed for the same job.
- Do not attempt to convert bromine pools to chlorine pools, even chlorinated salts. This is impossible. Dissolved chlorine will continue to regenerate bromine.
- There are certain benefits and disadvantages to using bromine. Some people find bromine better because bromine is generally less irritating to the skin and eyes. Many people with sensitive skin prefer bromine, but bromine is in the same group on the periodic table as chlorine, so it doesn’t help people who are allergic to chlorine. The weakness of bromine is that its cost is much higher than chlorine. Because bromine is more stable, it’s also more difficult to remove the smell of bromine from your skin or swimwear. In general, bromine is not a great alternative to chlorine for large pools, so you should consider bromine for small equipment such as hot tubs. Bromine is available in pellet form and can be added to lake water through a chemical feeder. Special note: you cannot stabilize bromine with cyanuric acid.
- You should hire professional testing service 3-5 times per season; they will certainly do more tests that are not commercially available: total chlorine and free chlorine, cyanuric acid, how acidic or alkaline the water is, adjusted total alkalinity, calcium hardness, water temperature (which makes a difference in the overall equilibrium level of water), total dissolved solids, iron, copper, quaternary ammonium mixture, or algaecide concentration.
- If chloramines or products combined with chlorine have a chance to build up, it will be difficult for you to break down or control them, causing the water to “smell”, cloudy, itchy eyes and skin, premature algae growth etc. . and lead to a lack of chlorine in the water. If the water is in a state of chlorine deficiency, it is difficult to keep the chlorine level stable, requiring you to add a very large amount of chlorine (adding about 22kg of chlorine or more to 75 cubic meters of water is normal). If the chlorine deficiency problem is not solved, the situation will get worse as the chlorine will combine to produce more and more chloramine. Special Note: most public (potable) water sources are being treated with chloramines, thus making this problem worse.
- To prevent scaling or creating an acidic environment, you should base on the Langelier saturation index to determine the overall balance of the water.
- Another possible substitute for chlorine is baquacil, the active ingredient of which is biguanide. This substance is less well known and more expensive, but it may be the best alternative for someone who cannot be exposed to chlorine because even saltwater pools produce chlorine. If you use a baquacil brand disinfectant, you can still use other brands to balance pH or calcium. Special Note: you cannot stabilize baquacil with cyanuric acid.
- Add borate at 50ppm to the pool as a pH control buffer, reducing pH fluctuations but also leaving the water soft and iridescent.
- Using a chlorine electrolyzer is another method of pool disinfection. Add some salt to the pool, then the salt is converted to chlorine in the tank’s control box, thereby helping to disinfect the pool. You only need to monitor the pH because the chemical reaction here will raise the pH and you need to lower the pH with “muriatic acid”. Improper installation of the salt/chlorine electrolyzer can cause pool problems such as pooling, rapid corrosion of metal parts and accessories, even stainless steel etc.
Warning
- Don’t add any chemicals too much.
- Add chlorine to water, not water to chlorine, as it can cause a violent chemical reaction.
- These chemicals are toxic, so keep them out of the reach of children.
- Always wait a minimum of two hours between different chemical additions to prevent negative chemical reactions and maximize the chemical’s effectiveness.
- Always follow the manufacturer’s instructions on the product label.
- Don’t do anything you don’t understand.
- Muratic acid is the best choice for lowering the pH, but it produces dangerous fumes that should be used with caution. Sodium bisulfate (pH or negative pH, granular) is the “safer” and household-friendly option.
