What happens if my pool has a low cyanuric acid?

Cyanuric acid (CYA) is a chemical that is added to swimming pools to protect the chlorine from the sun's ultraviolet (UV) rays. When CYA levels are low, the chlorine in the pool can be quickly depleted by the sun, making the pool less effective at killing bacteria and other contaminants. This can lead to a number of problems, including:

  • Increased risk of algae growth
  • Reduced effectiveness of chlorine
  • Skin irritation
  • Eye irritation
  • Respiratory problems

In addition, low CYA levels can also damage the pool liner and other pool equipment.

If you test your pool water and find that the CYA level is low, you will need to raise it. This can be done by adding a CYA stabilizer product to the pool. These products are available in both liquid and granular form.

When adding a CYA stabilizer to your pool, it is important to follow the manufacturer's instructions carefully. You will also need to test the pool water regularly to make sure that the CYA level is in the correct range.
