Cyanuric acid is a stabilizer for chlorine in swimming pools. It helps to prevent the chlorine from breaking down in the sun. While cyanuric acid is essential for maintaining a properly chlorinated pool, too much of it can cause problems.

What causes high levels of cyanuric acid?

There are a few things that can cause high levels of cyanuric acid in a pool:

* Adding too much cyanuric acid. This is the most common cause of high cyanuric acid levels. If you add too much cyanuric acid to your pool, it will not be able to dissolve and will build up over time.

* Evaporation. When water evaporates from your pool, it leaves behind the dissolved solids, including cyanuric acid. This can cause the concentration of cyanuric acid in your pool to increase over time.

* Using certain pool chemicals. Some pool chemicals, such as chlorine tablets, contain cyanuric acid. If you use these chemicals regularly, they can contribute to high cyanuric acid levels.

What problems can high levels of cyanuric acid cause?

High levels of cyanuric acid can cause several problems, including:

* Reduced chlorine effectiveness. Cyanuric acid can bind to chlorine, making it less effective at killing bacteria. This can lead to increased bacteria levels in your pool and a higher risk of swimming pool illnesses.

* Scale formation. Cyanuric acid can also contribute to the formation of scale on pool surfaces. This can make your pool look unsightly and can also damage the pool equipment.

* Cloudy water. High levels of cyanuric acid can also make your pool water cloudy. This is because cyanuric acid can react with other pool chemicals to form insoluble compounds that cloud the water.

How to lower cyanuric acid levels

If your pool has high levels of cyanuric acid, there are a few things you can do to lower the levels:

* Partially drain and refill your pool. This is the most effective way to lower cyanuric acid levels. However, it is also the most expensive and time-consuming option.

* Use a cyanuric acid reducer. There are several commercial cyanuric acid reducers available. These products work by breaking down cyanuric acid into smaller compounds that can be more easily removed by the pool filter.

* Wait for evaporation. If you do not want to drain and refill your pool or use a cyanuric acid reducer, you can simply wait for the water to evaporate. This will eventually lower the cyanuric acid levels. However, it can take several weeks or even months for the levels to drop significantly.

Preventing high cyanuric acid levels

The best way to prevent high cyanuric acid levels is to avoid adding too much cyanuric acid to your pool. Only add cyanuric acid when necessary, and follow the directions on the product label carefully. You can also reduce the risk of high cyanuric acid levels by using a pool cover to prevent evaporation and by avoiding the use of pool chemicals that contain cyanuric acid.

By following these tips, you can help keep your pool's cyanuric acid levels in check and avoid the problems that can be caused by high levels of cyanuric acid.
