There are several reasons why your pool water may turn green. Below, you will discover the most common reasons as well as the solutions to fix the problem. Hopefully, this article will assist you in understanding what causes your pool water to become green and how you can stop it once and for all!

Chlorine Stress

Chlorine is an essential element in the water that helps keep your pool water clean and healthy. Despite its usefulness, too much chlorine can do more harm than good. Too much chlorine in the water will cause the color of the water to become more vivid and will ruin the aesthetic appeal of your pool. Sometimes, the excess chlorine can even pose a safety threat to you and your family.

If you suspect that your pool water is becoming too chlorinated, then you need to find the source of the problem and solve it. One way of doing this is by adding more chlorine to the water yourself to flush out the existing bacteria and algae. Remember that too much chlorine in the pool water can be harmful, so make sure you keep a proper amount and don’t just add more to get the problem fixed. Too much chlorine will make the water undrinkable and could even affect your health. Adding too much chlorine to the pool will not only damage the pool’s water chemistry, but it will also affect the pool’s pH balance, leading to corrosion and damage to the pool equipment.

Algae Invasion

Just like with the chlorination of your pool water, too much algae can do more harm than good. In some cases, the algae will thrive in the water and multiply quickly, covering the entire pool surface area with a thick layer of green slime. Naturally, this will damage the aesthetic appeal of your pool and make swimming less enjoyable. In warmer climates, the algae will even begin to grow inside your pool, further causing you stress and headaches as you try to keep an eye on the pool’s environment and prevent any dangerous situations.

Just like with the chlorination of your pool water, too much algae in your pool can cause harmful algae blooms that will affect the eco-system and the wildlife that surrounds your pool. In some cases, this can even lead to an infection that affects humans as well. To fix this problem, you will need to remove some of the existing algae manually with a scoop or by using a pool vacuum. Just be sure to take proper safety precautions when handling this task as the algae can act as a natural pesticide and you don’t want to become ill from touching it or breathing it in.

Excess Phosphates

Another element that can cause your pool’s water to become green is phosphates. These are small mineral particles that help keep the algae and bacteria at bay. If your pool is surrounded by lots of grass and shrubs, then there is a good chance that the excess phosphates will accumulate there, making your pool water look dull and gray. In some cases, excessive phosphates can also result in sludge accumulating at the bottom of the pool, making the water murky and unappetizing.

To maintain healthy and clean pool water, you need to get rid of the excess phosphates by either installing a pool vacuum or by using a pool scrubber with the proper filtering system. Just make sure that the source of the problem is fixed before you begin using these items as they will only clean the pool water effectively when operated correctly.

Improper Water Temperature

One more thing that can cause your pool’s water to become green is the temperature of the pool water. When the water is warmer than 65 degrees Fahrenheit, then it will become more prone to algae growth and bacterium proliferation. In very hot climates, the water can even become too hot and pose a risk to your health. In this case, you need to either reduce the temperature of the water by opening up the pool cover or drain the pool and refill it with ice-cold water. In all cases, make sure that the water temperature is checked and taken care of every month, as this can prevent many algae-related problems.

To prevent too much algae growth, you can also use an algae control product or algae vacuum bag to clean up the pool water. Just make sure that you are applying the product to the entire pool’s surface area and remove any leftover residue with water testing and filtration. The algae control product will only work if you use it correctly and according to the instructions provided by the manufacture.

Poor Filtration

Filtration is very important in keeping your pool water clean and crystal clear. Without proper filtration, all of the aforementioned causes for your pool’s water to turn green will accumulate at the same time, resulting in a murky pool with an unappetizing tint. To ensure proper filtration, you must have a filter that is large enough to capture all of the solids in the water and a pump that is powerful enough to push the water through the filter system. To diagnose the root cause of the problem, you will need to inspect all of the parts of the filtration system, starting from the pool’s edge.

If you are finding that one or more of your pool’s filter components are malfunctioning, then it may be time for an upgrade. In some cases, this will mean replacing the entire filter system with a single filter that is powerful enough to stop even the smallest debris before it reaches the pool’s water. In other cases, it may mean simply changing out the defective parts and continuing to operate the pool as usual.

Water Testing And Filtration

Even if you are performing all of the aforementioned tasks and taking proper safety precautions, your pool water may become contaminated with algae and bacteria. To check for this, you must carry out proper water testing and filtration. In a case like this, you will need to draw some of the pool water into a container and test it for bacteria and algae growth. If you are finding that your pool water is contaminated, then you must immediately begin purifying it by either purchasing a pool vacuum or using one that you already own to suck up all of the debris from the water surface. To create the vacuum in your pool, connect the suction hose to the vacuum and place the nozzle at the surface of the water in the pool. Then, tighten the handle to create the vacuum effect. Switch on the vacuum to ensure that all of the water is being sucked up and then replace the pool surface water with fresh, clean water.

Once you have replaced all of the contaminated water with fresh, clean water, then you can begin the process of eliminating the source of the contamination and reestablishing proper water chemistry in your pool. If possible, test the water once a week for optimal results.
