How do I lower the cyanuric acid in my pool?

Is it safe to swim in a pool with high cyanuric acid?

Although cyanuric acid offers a low level of toxicity without any serious health concerns, having high-levels of this chemical in a pool puts people at risk because of the chlorine’s diminished ability to eliminate bacteria and viruses.

What raises cyanuric acid in a pool?

Cyanuric acid levels are raised by adding pool stabilizer. It’s called stabilizer because cyanuric acid stabilizes free chlorine from being evaporated by the sun. For more information, check out The Relationship Between Swimming Pool Chlorine and Cyanuric Acid.

What happens when cyanuric acid is too high?

When cyanuric acid levels get too high, it can cause something referred to as chlorine lock, which basically means your chlorine has been rendered useless. You’ll know it has happened when your chlorine test shows very or little chlorine even right after you’ve added it to the pool.

What neutralizes cyanuric acid?

Dilute your pool water if the levels are above 80 ppm.

The easiest way to lower the levels of cyanuric acid in your pool is to simply dilute the water. Partially drain your swimming pool by the same percentage by which you want to reduce your cyanuric levels.

Does shock raise cyanuric acid?

Cyanuric acid is also known as a Stabilizer, it helps the chlorine stay in your water. … When you “shock” continuously what you’re doing is you are actually increasing the Cyanuric acid levels steadily but the chlorine levels go up fight off what they need to then they come right back down.

Will CYA go down over time?

When water evaporates, CYA stays behind and stays in the water for a long, long time. This can be considered a benefit for some…but it can also be a problem down the road, because the CYA will accumulate. For the most part, CYA levels can remain very stable if you’re not adding more of it to the water.

Does cyanuric acid damage pool liner?

And stabilized chlorine (like dichlor or trichlor) already comes with CYA, so you’ll likely be adding it to your pool water throughout the season. Because CYA is an acid, you’ll need to handle it carefully. It can damage your filter and your pool, especially if you have a vinyl liner.

What should cyanuric acid levels be in a pool?

In fact, cyanuric acid has been known to stay in pools even after completely draining them – it can get into the plaster. The only way to lower the levels is to drain some water and add water with no CYA in it.

Does baking soda lower cyanuric acid?

Liquid chlorine and granular chlorine such as a calcium based product, does not contain CYA . … It reduces chlorine dissipation from heat and UV rays. Sodium bicarbonate will raise your alkalinity and slightly raise your pH-so add small amounts and re-test after a few hours to make sure you hit your mark.

Do chlorine tablets have cyanuric acid?

Stabilized chlorine tablets contain cyanuric acid, which will protect the chlorine from being broken down by the sun’s UV rays. This is especially important in an outdoor pool. With no CYA you’ll constantly be adding lots of chlorine.
