Should I Use Cyanuric Acid Stabilizer In My Indoor Pool?

Cyanuric acid, also known as stabilizer or conditioner, is a chemical commonly used in swimming pools to protect chlorine from the degrading effects of ultraviolet (UV) rays. However, the use of cyanuric acid in indoor pools has sparked a debate among pool professionals the world round. Is cyanuric acid recommended in an indoor pool or should it be avoided? In this article, we will explore:

• What Does Cyanuric Acid Actually Do?
• Is Cyanuric Acid Effective In Indoor Pools?
• Potential Drawbacks From Using Cyanuric Acid In Indoor Pools
• Local Regulation For Or Against the Use of Cyanuric Acid in Indoor Swimming Pools

So, let's dive in and explore this divisive yet important topic!

What Does Cyanuric Acid Actually Do?

Cyanuric acid is added to pool water to stabilize chlorine, meaning it slows process of the pool's chlorine from breaking down under UV light, most commonly coming in the form of sunlight. Cyanuric acid can be especially important in outdoor pools exposed to direct sunlight. The chemical forms a protective barrier around the chlorine molecules, prolonging their effectiveness and reducing the need for frequent chlorine additions.

Is Cyanuric Acid Effective In Indoor Pools?

One of the primary arguments against using cyanuric acid in indoor pools is the absence of direct sunlight. Unlike outdoor pools, indoor pools are shielded from UV rays by the building structure. Since UV protection is really the only reason for the use of cyanuric acid in the first place, it can easily be argued that it isn't necessary in an indoor pool. 

Now that we know that cyanuric acid isn't necessary to use in an indoor pool, it's important to take the conversation one step further and discuss how adding cyanuric acid to your indoor pool might actually hurt more than it helps. 

Potential Drawbacks of Cyanuric Acid In Indoor Pools

It is critical to keep in mind that excessive levels of cyanuric acid (the exact number for an "excessive level" is hotly debated) can lead to water conditions where the chlorine becomes less (or totally) ineffective in sanitizing the pool water. This can result in the easy spread of harmful recreational water illnesses & the uncontrollable growth of algae.

For this reason, it is not recommended to add cyanuric acid or use any products that add cyanuric acid to indoor swimming facilities. 

Regulatory Considerations

In some regions of the US, regulatory bodies even have guidelines or restrictions on the use of cyanuric acid in indoor pools. It is essential for pool operators to be aware of local regulations and consult with pool maintenance professionals in your area to ensure compliance with any local laws or statutes regarding the use of cyanuric acid in indoor swimming pool facilities.
