Free chlorine is an important disinfecting component of pool water. The free chlorine level in a pool is affected by sunlight and contaminants in the water. So it is necessary to test and replenish the free chlorine regularly. When free chlorine levels are low, bacteria and algae grow, resulting in uncomfortable feelings and infections. If your pool's chlorine levels are consistently low, there are several factors that could be causing the problem. Here are the most common reasons:
1. Chlorine is consumed in large quantities
When there is a lot of organic matter in the pool, such as leaves, debris, algae, and even sunscreen and sweat from swimmers, there is an increased demand for chlorine. Chlorine is quickly consumed to break down these contaminants.
A large number of swimmers can also cause chlorine levels to drop faster.
2. Sunlight exposure (UV degradation)
Chlorine is sensitive to the sun's ultraviolet rays, which can cause it to break down quickly. If the pool is exposed to a lot of direct sunlight and there is no stabilizer (such as cyanuric acid) to protect the chlorine, the loss of chlorine will be faster.
3. Low cyanuric acid levels:
- In outdoor swimming pools, it is critical to maintain proper cyanuric acid levels. If the level is too low, the chlorine will break down faster. On the other hand, levels that are too high can reduce the effectiveness of chlorine, causing more chlorine to be needed.
4. Algae Growth:
Algae can consume chlorine quickly. Even if you can't see visible algae, small amounts of algae can cause the chlorine to be quickly depleted. Biofilm is another possible cause.
- Treating your pool with an algaecide or shocking it can help with this issue.
5. Heavy Rain or Water Dilution:
Rainwater can dilute the chlorine concentration in your pool, especially in areas that experience frequent heavy rains. Additionally, rainwater can introduce contaminants that deplete chlorine.
- If you frequently add fresh water to your pool, this can also dilute the chlorine levels.
6. Poor Circulation:
Proper circulation is key to evenly distributing chlorine throughout your pool. If your pool's pump or filtration system isn't working effectively, some areas of your pool may be experiencing low chlorine levels, leading to low chlorine levels overall.
Addressing these issues may help stabilize your chlorine levels.
How can I boost free chlorine?
If you notice consistently low chlorine readings, check your Cyanuric acid levels. Low cyanuric acid levels mean your chlorine is vulnerable to damage from the sun's UV rays. So your chlorine will burn off faster. To maintain chlorine levels consistently, you may also consider using a stabilized chlorine product like sodium dichloroisocyanurate and trichloroisocyanuric acid (TCCA) tablets.
If there are a lot of swimmers or debris and organic contaminants in the water, more chlorine is needed to properly disinfect the water. At some point, your chlorine is used up faster than you can add it, and your chlorine levels remain low. Again, shocking your pool can help with this.
Keeping your pool's chemistry balanced is an important step in pool use and maintenance. If you have no experience maintaining your pool, to determine the exact cause of the chlorine problem, you may need to test your pool water and consult a pool professional. They can help you identify the underlying problem and recommend an appropriate solution. When it comes to pool chemicals, we can provide you with a more suitable solution for you.
