Maintain balanced chlorine levels with 3-inch tabs: 1 tab/10,000 gallons, weekly monitoring, and automated systems for 1-3 ppm in pools.
Chlorine plays an important role in ensuring the safety and health of swimming pools. The ideal level of chlorine in swimming pools is required to be 2-4 parts per million (ppm). This range will make the water disinfected effectively, free from bacteria and other pathogenic microorganisms, and safe, as well as comfortable for swimming.
Why 2-4 ppm Chlorine is Necessary
To begin with, 2-4 ppm chlorine level keeps swimming water safe, eliminating bacteria, and other pathogenic microorganisms. When the chlorine level is below 2 ppm, the probability of bacterial breeding is too high and can cause swimmer’s ear among other infections. On the other hand, if it is more than 4 ppm, the water becomes ineffective in disinfecting and the additional concentration may cause skin irritation and damage the pool equipment.
Efficacy of Chlorine Disinfection by pH
The efficacy of chlorine as a disinfectant in swimming pools is significantly determined by pH. A swimming pool’s ideal pH is 7.2 to 7.6. When too low, below 7.2, the water is acidic, leading to a high rate of chlorine evaporation, which becomes less effective. On the other hand, when it is too high, over 7.6, the water is alkaline, causing the formation of combined chlorine, which is less effective and dangerous leading to respiratory issues that may not be effective while sanitizing, increasing irritation while swimming. Notably, combined chlorine is ineffective as a sanitizer. Therefore, higher chlorine levels can be diluted by adding more water but not advisable for they are getting weaker and less effective. Regular testing must be done and if the level is lower than 2 pp, add more chlorine to between 2 and 3 ppm and use a feeder or partially add to adjust water further.
The correct procedure for adding chlorine to your pool is:
Types of Chlorine
There are three main types of chlorine for pools, tablets, granules, and liquid; each of them has its handling benefits and is designed for different pool sizes and varieties. Since the resin and ceramic pools should not be exposed to direct contact with the ground, tablets and granules are best suited for them. Because of their easy handling and slow release, chlorine tablets and granules are the most popular choice for homeowners. To ensure best use of chlorine tablets and granules, you should:
How to Safely Shock Your Pool with Higher Amounts of Chlorine
Pool shocking involves adding an elevated amount of chlorine to the pool to rapidly eliminate organic waste. The correct pool dose for shocking is 1-2 ppm in chlorine after the addition; however, you should always consider the manufacturer’s instructions. In addition, it is vital to test the pool after shocking with high amounts of chlorine to make sure that the level has returned to the safe zone.
You should follow the best practices for pool chemical treatment by:
Daily Testing Recommendations
Based on the above analysis, you may consider daily testing for:
For your benefit and the benefit of your customers, it is important to have a clear understanding of these differences to avoid making any unnecessary investments. For example, you may want to consider using a test kit that is not specifically designed for use in a pool with high bather usage.
Tips for Using a Test Kit or Test Strips
When using a test kit or test strip:
Post-Testing Treatment for Chlorine Levels
After testing, if the chlorine level in your pool is incorrect:
There are several common misconceptions that you need to address in order to properly groom your pool. One of the most common is the belief that more is always better when it comes to chlorine. While chlorine is an essential and effective pool cleaner, it is important to maintain the proper balance of water in your pool in order to ensure that it is safe for swimming. Additionally, you should regularly clean all pool equipment.
Unhelpful Misconceptions
Another common misconception is that cloudy water is a sign of having too much chlorine in your swimming pool. However, this is usually not the case, as the main causes of cloudiness are inadequate filtration or algae growth.
Expert Pool Tips for Chlorine Tablet Use
The tablets should always be stored in a cool, dry place in order to ensure that they do not begin to dissolve sooner than expected. You should also clean the feeder in order to provide an even flow of chlorine.
One of the most common mistakes people make when using chlorine is over-chlorination. The chlorine levels in your pool are based on the size and makeup of your specific swimming pool, so it is important to not go over the suggested dose. Similarly, always follow the instructions on the bottle for ways to properly dilute the chemical. Finally, never mix chlorine with other chemicals.
