A dirty and green pool

Before we dive into how to clean a green pool fast, we need to understand why it turned into that hideous color in the first place.

Most of the time, a pool turning green is because of algae overgrowth. Of course, that isn’t the only reason. Here are some of the most common causes of swimming pools turning green:

  • Imbalanced pH Levels: A pH level that is too high can cause a lot of issues for your pool. If the pH level is too low, it can cause the materials in the pool to erode and cause eye irritation. If the pH level is too high, bacteria and algae get the chance to not only survive, but also thrive in the pool. If your pool is turning green, the pH level is probably out of balance and may be too high.
  • Change in Weather: Changing weather can also lead to the green color. It gives algae a better environment to grow in. Humidity and moisture is already there in the pool. Add warmth to it and there is the chance of algae buildup.
  • Clogged Filter: If the filter isn’t working properly, it can allow algae to continue growing. It also leads to bacteria easily breeding in the water to further discolor the water.

Here are some steps you can take, to clean a green pool fast:

Lower The pH Level

When you start trying to clean your pool, the first thing you need to do is balance out the pH level. The pH level of the pool should not be too acidic (low pH) or too alkaline (high pH) in nature. Ideally, you should have the pool water at 7.8 pH, which is slightly alkaline.

Balancing the pH level is easy. Turn on the pump so that the water circulates throughout the pool. The pH level is typically high when it allows algae to fester in the water, so you should bring it down by adding sodium bisulfate. After letting the chemical circulate and react with the water, test the water to see if you need to add more.

Shock The Algae Out

With the pH level no longer a problem, you need to remove the algae that are already there. Removing algae is a matter of shocking it out. This does not mean to apply an electric current. Add a pool shock. This chemical mixture contains high levels of chlorine, which immediately takes action to wipe out algae and clear up the pool.

Use a powerful pool shock, preferably something that contains over 70 percent available chorine, for the most effective results. The water might initially look quite dirty but as the water passes through the filtration system, it will clear up and leave you with a beautiful blue pool.

Flocculant

With the algae dead but still floating inside the pool, you might think the next step is to vacuum the dead algae out & you're good to go. However, it's not as simple as that - algae are incredibly small, and almost all of them will pass straight through your pool's filter and straight back into the pool. In fact, if you just vacuumed without taking any other steps, your pool could easily look more cloudy than before, as all the algae would have been stirred up!

To get around this problem, add flocculant to the water. This will accumulate all the contaminants in the pool and form clumps, which are large enough to be caught by the pool filter. As you let the filtration system clear out the water, use a brush to wipe the algae off the pool’s surfaces and a vacuum to suck it all out.

Remember to clean or backwash the filter once you've got rid of all the algae!

Run Your Filter

If there is a chance that your filter wasn’t working properly, that can also result in the buildup of algae. Make sure you get the filter in your pool checked, maintained and cleaned out after shocking the algae. Once you know that the filter is working properly, turn it on and let it sort out the algae.

Stop The Algae From Returning

Within a few hours, you will have a clean and clear blue pool from what used to be a disgusting green. These steps on how to clean a green pool are effective, reliable and incredibly fast. Use them to get rid of algae from your pool.

The last thing you need to do is make sure that you keep up with proper maintenance of your pool. Get the filtration system checked on a regular basis, ensuring it is well-maintained and check the pH levels. Keep the chemicals on hand in your storage room so that you can correct the pH levels in case of any imbalance. Keeping in mind these tips, you can successfully keep your pool algae-free!
