If you are a residential or commercial swimming pool owner, you might have heard of phosphates. But what exactly are they, and why do they matter? The answer lies in the quality of your pool water. A buildup of phosphates leads to poor water chemistry, potentially leading to other issues like algae growth and cloudy water. In this article, we will discuss what phosphates are and how to remove phosphates from a pool with the help of phosphate removal products.

What are phosphates?

Phosphates are naturally occurring compounds found almost anywhere – from soil to food. They are also in several pool chemicals, such as algaecides and fertilizers. When these chemicals accumulate in your pool water, the phosphate levels increase and can lead to unwanted consequences. Algae growth in your pool is a common problem arising from excess phosphates. Therefore, it is essential to manage your phosphate levels to keep your swimming pool water safe and healthy.

Why remove phosphates from a pool?

As mentioned earlier, phosphates can lead to trouble – algae growth, green water, and cloudiness. They can also reduce the efficacy of sanitizers and other pool chemicals. Removing phosphates from the water can help minimize any unpleasant odors or build-up along the pool walls if you have an indoor pool. Therefore, removing phosphates is crucial to maintaining water clarity, sanitation, and healthy pool water.

How to remove phosphates from a pool?

Using a phosphate remover product is the most effective way to remove phosphates from your pool. These products break down and dissolve the phosphates in your pool water. Most phosphate removal products contain enzymes that digest and remove phosphates from the water. You can also perform a backwash and rinse to remove excess phosphates from the filter. However, it’s imperative to note that using a phosphate remover is not a one-time solution. Continually using a phosphate removal product can help maintain low phosphate levels in your pool.  

When to use a phosphate remover?

Test your pool water regularly for phosphate levels. A good rule of thumb is to use a phosphate remover if your phosphate levels exceed 125 ppb (parts per billion). For outdoor pools, it’s recommended to use a phosphate remover during the start-up of the pool season, in mid-season, and again in August or September. For indoor pools, using a phosphate remover during the pool shutdown before opening is recommended to get rid of any accumulated phosphates.
