Understanding pool fundamentals is crucial before getting into the in-depth analysis of why a swimming pool turns green after shocking. Let’s get to the Pool Shocking first!
What is Shocking?
Most of the first time pool owners don’t know what shocking exactly is and often get confused. So for those of you who don’t know, “Shocking” is the process of adding appropriate levels of chlorine or non-chlorine chemicals to the pool.
It is done to raise the “free chlorine” levels. The objective of shocking is to raise it to a point where contaminants such as algae, chloramines, and various forms of bacteria are destroyed. This process makes the pool safer.
Why Your Swimming Pool Is Turning Green After Shocking
But the question is raised, why does it often turn pool still green after shock, leaving pool owners perplexed even after shocking? It is one of the most common questions asked by pool owners. The simple answer is – It is because of algae, fungi, and the excess copper levels dissolved in water.
Excess of wrong chemicals may also be the cause of turning the pool cloudy and green. It is crucial to fix the problem otherwise the pool doesn’t look healthy and pleasing. If you have guests or family members visiting, then it may not be a good experience for them.
What are the Fators of Pool Turn Green Even After Process of Adding Tons of Chemicals
Here are some of the main reasons why your pool may turn green even after you’ve exhausted the process of adding tons of chemicals.
Stabilizers – Factor of Green Color Pool
Keep a check on levels of the stabilizers by adding the tablets (cyanuric acid). It can usually become elevated over time and lock their molecules of CL2.
If you get a very high chlorine reading on your test kit, then the chlorine is simply not working effectively at killing algae because it’s just not in the right chemical composition.
Phosphates – Factor of Green Color Poo
High phosphate levels can also result in algae problems. Phosphorus or phosphate thus enters the pool by leaching the leaves or other forms of organic debris in the pool.
It usually results in incorrect levels of phosphate, which ends up leaving a green color in the pool.
Whether you believe it or not, not adding chlorine will also turn the water green. But pool water must have a sanitizer or something that kills bacteria and algae. Algaecide without chlorine may not prevent the pool from turning green.

So now that you understand the importance of adding the right levels of chemicals to get out of this problem, you may try the different combinations or add the right amount of chlorine, algaecides, and other required chemicals to ensure clean and healthy water in your swimming pool.
You should test the water 24 hours after the shocking process and start adjusting the pH and alkalinity levels. The levels of chlorine may still be elevated, however over a few days, it would stabilize.
Experts advise adding sodium thiosulfate to reduce the chlorine levels, but remember adding too much of thiosulphate can cause the chlorine level to destabilize.
Once the shocking process is over, you need to set your pump timer, so the pool is properly filtered for a long enough time to effectively deal with any algae or any debris left in the pool.
