A pool with clear water represents chic, relaxation, and enjoyment, but observing the water become green can be alarming. You might expect that adding chlorine would fix this problem, but many pool owners are surprised, "Why is my pool green even when the chlorine level is high?"
In this post, we'll examine why your pool can still become green even with proper chlorine levels and the expert services provided by Anomaly, a reputable pool maintenance company.
Algae is the most extensive source of green swimming pool water. Algae develop in water with favorable circumstances for growth, such as warm, dead, or unbalanced water. Although chlorine is a powerful sanitizer, mustard algae in the pool can grow if specific parameters are not maintained or external influences impact the water quality.
A variety of factors can contribute to green color of pool water, including:
Chlorine is a vital ingredient used to clean swimming pools. It functions as a sanitizer, eliminating hazardous bacteria, viruses, and algae that can grow in water. A proper chlorine level typically prevents mustard algae growth in a swimming pool, keeping the water pure.
Chlorine mixes and breaks down organic pollutants. This process produces chloramines, which release a strong chlorine smell and limit chlorine's power. Free-available chlorine (FAC) remains active in the water, ready to tackle new pollutants.

A high chlorine level should prevent algae from growing. Pools can still turn green even when the chlorine levels are within the recommended limit. This could happen for several reasons:
Chlorine lock occurs in the pool when the chlorine in the water becomes ineffective due to the presence of too many pollutants, or when the water contains an excessive amount of stabilizer (cyanuric acid). When this occurs, chlorine cannot function, and algae might begin to grow.
If the water pH is too high, chlorine becomes significantly less effective at sanitizing the pool. The optimal pH range for pool water is 7.2–7.6. When pH levels rise above this range, the efficiency of chlorine decreases, allowing algae to grow even at high chlorine levels.
Organic material, such as leaves, insects, and oils from swimmers, can collect in the pool and consume the available chlorine. If this occurs sooner than chlorine can cheapen the components, algae may begin to grow. Poor cleaning habits and not having the best water filtration system often contribute to this problem.
Even with high chlorine levels, a pool requires proper circulation to distribute the chemicals throughout the water correctly. Poor water circulation can result in "dead zones" where chlorine cannot reach, allowing algae to grow.
Phosphates, which enter pool water via leaves, fertilizers, and even some pool chemicals, provide a food source for algae. High phosphate levels can promote algae growth even when chlorine levels are normal or higher.

Aside from chlorine concerns, various other things can contribute to your swimming pool green color.
As previously stated, high pH levels can prevent chlorine from operating effectively. To keep your pool clear and algae-free, test the water pH regularly and modify it with pH increasers or reducers.
Your swimming pool pumps and filter system are essential for keeping the water clean. If the system isn't working efficiently or long enough, water won't circulate properly, and debris will build up, resulting in a green swimming pool.
When phosphorus levels are high, keeping the pool clean is difficult. Phosphorus can enter the pool from various sources, including organic debris and polluted water.
Rainwater can carry debris, pollutants, and algae seed into the pool. Furthermore, rainwater is generally slightly acidic, which can lower the pool's pH and reduce chlorine efficiency, resulting in green water.

Managing a green pool requires several approaches. It is crucial to test and balance the pool water, shock the pool when needed and verify that the filtration system is functioning properly.
Evaluate the pool water's chlorine, pH, alkalinity, and phosphate levels. If the chlorine level is high but the pH is out of balance, use the required pool cleaning chemicals to adjust it. The optimal levels should be:
If green algae is continuously growing in a pool, then a chlorine shock treatment may be required. It involves adding a significant amount of chlorine to the pool to boost the chlorine level and algae kill quickly for the pool. Always follow the manufacturer's recommendations for the appropriate quantity of shock based on your pool size.
After shocking the pool:

If your swimming pool color always green after shocking, it could be due to poor filtration, high phosphate levels, or an imbalanced pH. Testing the water and running the filter system continually after aftershocks is crucial.
Swimming in green pools is not recommended. Algae can carry hazardous germs, and the water's chemistry is likely imbalanced, maybe causing skin irritation or disease.

You should test your pool water at least once a week to ensure that the chlorine levels and pH are within suitable limits. More regular testing may be required during hot weather or heavy pool use.
Although home bleach contains chlorine, it is not designed for pools and lacks stabilizers. Pool-grade chlorine products are preferable for pool care.
Baking soda does not kill algae, but it can help improve the pH and alkalinity of your pool water, making chlorine or algaecides more effective.
A pool is green but chlorine is high, typically caused by other issues such as pH is low or high, poor circulation, or the presence of phosphates. Proper water chemistry, fixing equipment faults, and seeking professional assistance from professionals such as Anomaly Pool Services can help you enjoy a sparkling, algae-free green to blue swimming pool all year.
