How Long Does It Take to Clear a Green Pool?

Pool water can sometimes turn green, which could be due to high chlorine levels or the growth of algae. How long it takes to clear a green pool can vary greatly depending on the severity of the green algae problem and the methods used to address it. This article will explore the steps to clear a green pool and the timeline involved in each step.

Assessing the Greenness and Cloudiness

First, it is important to assess the severity of the greenness and cloudiness. Green pool water can range from a mild algae presence to a significant overgrowth, while cloudiness can be a result of dead algae, high iron content, or other contaminants.

Preparation and Initial Steps

Before beginning any treatment, it is crucial to quantify the extent of the problem. This involves understanding the size of the pool and the type and efficiency of the filtration and sanitization systems in place. The size and type of pool, along with the willingness of the pool operator to monitor the process regularly, will also influence the timeline.

One common method to clear green pool water is to shock the pool with a high dose of chlorine. Typically, a second high dose is administered after 8 hours. The filter should be changed and then cleaned twice daily until the water is clear. This process may take anywhere from one to two days at best.

Effective Algae Removal Techniques

For pools with heavy algae growth, the easiest solution is to drain the pool, power wash the surfaces, and refill it. This method will effectively eliminate algae but can take several days due to the drainage, power washing, and refilling processes.

For pools with a small amount of algae, a shock treatment or a double shock treatment can help eliminate live algae in a day. Dead algae will settle to the bottom and can be removed using a pool vacuum. However, depending on the filter system, some of the vacuumed detritus will re-enter the pool, causing cloudiness. Vacuuming directly to the waste line can help remove algae detritus. Adding a clarifier can also help in removing remaining cloudy material in the water. Clarifiers often require up to two days to fully take effect.

Addressing High Iron Content

In some cases, green pool water can be a result of high iron content, leading to a cloudy, green appearance similar to that of the Rio Olympics. Sodium bicarbonate or sodium carbonate, commonly known as pH plus, can be added to form a colorless complex with the iron, resulting in clear, colorless pool water.

The timing for clearing a pool can vary significantly depending on the severity of the problem. A small amount of algae can typically be cleared in one to two days, while heavy contamination might take up to a week. In some cases, draining and refilling the pool can take several days to two weeks, depending on the pool size and the pump's capacity. Filling a smaller pool using a common garden hose can take several days, and in some areas, your local fire department can refill a pool from a fire hydrant. Pool owners with well water will usually have water brought in in tanker trucks.

Preparation, monitoring, and the proper treatment methods are key to effectively clearing a green pool. By assessing the problem and following the appropriate steps, you can ensure a clear and healthy pool environment for you and your family.

Conclusion

Clearing a green pool can be a challenging task, but with the right steps and the right timing, you can achieve the clear and pristine pool you desire. Whether it's through shock treatments, algae removal, or addressing high iron content, the timeline can vary. Proper planning and professional guidance can help ensure a successful and efficient process.
