How much chlorine do you add to a spa pool?
Chlorine is an important part of the spa pool experience when it comes to cleanliness and hygiene.
Add 1.5 teaspoons of chlorine granules for every 1,000 liters of water in your spa pool. The goal is to keep the chlorine level in the water between 3-5 ppm for maximum safety.
Chlorine is what keeps your spa pool free of bacteria and other substances and helps make your spa pool a safe place to soak in every time. Getting the chlorine level right in your spa pool is critical to keeping it clean and safe.
Why do spa pools need chlorine?
Because the water is warm, spa pools may have more bacteria and debris than you first think.
Spa pools can collect skin and hair products, body oils, lotions, dirt, debris, and other unwanted particles over time.
There are three ways to prevent bacteria that lead to an unpleasant spa pool experience:
- Adding chlorine granules and maintaining the appropriate level of chlorine
- Periodically clean and replace the filters
- Routine draining and cleaning of the spa pool itself using spa chemicals and other household cleaning supplies
Chlorine plays a vital role as it is what keeps the spa water free from the daily build-up of bacteria. It is one of the most effective chemical products available and works in conjunction with filters to keep your spa pool clean.
Chlorine granules are a popular choice because they dissolve easily. It can be used for a spa shock dose.
How much chlorine granules should be added to a spa pool?
Chlorine granules raise chlorine levels much faster than chlorine tablets, so it’s important to get the right dose. The granules are sprinkled directly into the water, so the process is relatively easy.
With the jets on, add chlorine directly to the filter housing of your spa pool, but keep the granules away from the surface of the spa pool as they can damage the acrylic of the spa shell. Also, the water temperature should be above 20 degrees Celsius to avoid damage.
If you are not sure about the water temperature, you can dissolve the chlorine beads beforehand to avoid any danger or damage, especially if you have just filled your spa pool with fresh water.
Add some water to a plastic bucket and then mix in the chlorine granules. Once they are dissolved, you can add pre-dissolved chlorine to your spa pool. It is best to distribute the water closer to the spa pool pumps and inlets so that the chlorine mixes with the water faster. Make sure the jets are fully on.
Because chlorine granules dissolve quickly and increase chlorine levels, it’s important to know the water volume of your spa pool. Once you know how many gallons your spa pool holds, you can add the amount of chlorine granules.
For weekly dosing, the general ratio is about 1.5 teaspoons of chlorine per 1000 liters of water to achieve 3-5 ppm chlorine. After each use, it is recommended to use ½ teaspoon as a supplement to maintain hygiene, especially if the spa is used frequently. If needed, you can dose with ½ teaspoon of granulated chlorine once a week and test the water to ensure proper chlorine levels.
If in doubt about how much chlorine granules to add, go slow!
Too much chlorine is not good for spa pools, so it’s best not to overdo it. You can slowly add the chlorine granules, let them dissolve, and then measure the chlorine level to get the right level.
How often should I add chlorine granules to spa pools?
The amount of chlorine granules added and its frequency depends on your use. “Shocking” the water with chlorine should be done at least once a week or more, depending on how often the spa pool is used.
The term shocking basically refers to adding some chlorine to mix with any bacteria or oil in the water.
Once combined, you can add more chlorine to get rid of the mixture you’ve created – effectively killing the bacteria. Doing this will also help ensure that your spa pool has balanced water.
Add a small amount of chlorine between shocks to keep the surface safe. The chlorine level should be between 3 and 5 ppm.
For freshwater salt systems, be sure to test the chlorine regularly and adjust the output level as needed. Concentrated chlorinating granules or liquid chlorine can also be added as a supplement.
Test the water using a test strip to monitor the chlorine level and adjust as needed.
Adding chlorine granules to your spa pool keeps it safe and ready to use anytime! Paying attention to chlorine levels is very important for overall health and safety. The more a spa is used, the more chlorine products you should probably add to it.
Having a regular schedule for monitoring chlorine levels, filtration systems, draining the spa, and replacing it with fresh water should all be part of overall maintenance.
