Particularly during the hot summer months, pool water turning green is a common problem. Not only is it unsightly, but it can also be a health hazard if left untreated. If you are a pool owner, it is vital to know how to fix and prevent your pool water from turning green again.
In this article, we will analyze the possible factors and solutions for your pool turning green.
Reasons Why Pool Water Turns Green
Understanding the reasons why your pool water turns green is crucial to preventing this from happening. This phenomenon is generally the result of algae growth, which can be caused by multiple factors. For example:
① Insufficient free chlorine in the pool
If the free chlorine in the pool is not replenished in time after consumption, or if the excessive cyanuric acid produces “chlorine lock” phenomenon, the disinfectant will be insufficient and unable to kill microorganisms.
② Due to hot weather, microorganisms grow wildly, causing chlorine to be consumed too quickly without timely replenishment.
③ After a heavy rain, the effective chlorine in the swimming pool will decrease, and rainwater will bring spores into the swimming pool.
Green swimming pool solutions
When your pool algae grows wildly or even turns green, don’t worry, you can take some measures to fix it. Start with the following aspects and you will regain a clean and healthy pool.
① First of all, before doing anything, you must first determine the chemical level of your pool water, so testing the water quality is the first step. Use a test strip test kit to check the pH value. Adjust the pH value to between 7.2-7.8.
② Clean the floating debris in the water and use the pool cleaning robot to absorb and remove the debris after scrubbing the pool walls and bottom.
③ Chlorine shock. Kill algae in the water with chlorine shock. Follow the requirements in the operating instructions and make sure to add the amount suitable for your pool.
④ Flocculation. After treatment, the pool will be turbid to varying degrees due to dead algae. Add pool flocculants to make the killed algae and impurities in the pool water condense and settle to the bottom of the pool.
⑤ Use a pool cleaning robot to absorb and remove the impurities that have settled to the bottom. Make the water clear and clean.
⑥ After cleaning, wait for the free chlorine to drop to the normal range and retest the pool chemistry level. Adjust the pH value, available chlorine content, calcium hardness, total alkalinity, etc. to the specified range.
⑦ Add algaecide. Choose an algaecide suitable for your pool and put it into the pool and circulate it. The purpose is to prevent algae from regenerating.
Note:
Remove leaves and other floating objects from the pool every day. It is much easier to remove them before they sink to the bottom of the water.
When using pool chemicals, take precautions and avoid direct contact with the skin.
Please use accurate measurements according to the instructions to avoid unnecessary trouble.
Pool maintenance is an important and tedious task. If you encounter any problems, you can communicate with a pool maintenance expert in time. If you need any pool chemicals, please email me immediately. （info@xingfeichemical.com）
