Does CYA Break Down?

Why is high CYA bad?

The only “bad” aspect of a high CYA level (over 100 ppm) is that the Total Dissolved Solids (TDS) will escalate, interfering with the chlorine’s bacteria and algae killing ability.

Sometimes high levels of CYA can cause a condition called “purple” or copper cyanurate..

How much cyanuric acid is too much?

As long as the cyanuric acid concentration is less than 20 mg/l, there will not be any problem. Once a level of 70 mg/l is exceeded, cyanuric acid becomes problematic. Too high a concentration can, however, easily be solved. All you need to do is add fresh water to the pool (3 to 5% of the total volume).

Can I shock pool after adding stabilizer?

8) How long after adding chemicals can I swim? Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals. Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool.

How long does it take for CYA to dissolve?

Let the chemical dissolve into the water after pouring it into the bucket. This process could take anywhere between ten minutes to a few hours, completely depending on the amount of cyanuric acid (CYA) you are trying to dissolve.

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.

How long does CYA last in pool?

It can take up to 12 hours for a 20 ppm chlorine level to kill it. CYA just slows that process down.

Is CYA 100 too high?

If your cyanuric acid level was at 100 ppm (way too high), and you want to lower it to 50 ppm, you will need to replace half the pool water (assuming your fill water has 0 ppm of CYA).

Does cyanuric acid break down?

Degradation also proceeds in 3.5% sodium chloride solution. Consequently, there are degradation pathways widely available for breaking down cyanuric acid discharged in domestic effluents. The overall degradation reaction is merely a hydrolysis; CO2 and ammonia are the initial hydrolytic breakdown products.

How do I lower the cyanuric acid in my pool without draining it?

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.

Is cyanuric acid dangerous?

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 kill bacteria and viruses.

What should my CYA level be?

Experts recommend between 30 and 50 ppm CYA for the right balance, and regulation requires less than 100 ppm CYA. But what happens when your pool’s levels rise above this? The chlorine can’t do its job – it’s bound to the CYA, instead of being free and available to sanitize and oxidize. That makes for a germy pool.

Does cyanuric acid affect pH?

The fraction that ionizes is pH-dependent. … At ideal pH (7.4 to 7.6) and cyanuric acid levels (30 to 50 ppm), the cyanuric acid/cyanurate system will not significantly contribute to the buffering of pool water. However, as the cyanuric acid levels increase, they will have an effect on the total alkalinity test result.

Does pool shock have cyanuric acid?

Sodium Dichlor: Dichlor for short, is stabilized pool shock, with cyanuric acid as protection from the sun. 56% strength, with a nearly neutral pH level.

What is the correct level of cyanuric acid in a pool?

Saltwater pool manufacturers recommend maintaining cyanuric acid levels around 60-80 ppm. This is a bit higher than the 30-50 ppm range recommended for non-saltwater pools. And if you live in an area where your pool gets a lot of direct sunlight, you may even consider bumping your cyanuric acid up to 80-100 ppm.

What happens if you swim in a shocked pool?

Chlorine- based shock contains high levels of pH and will alter both your pH and chlorine levels in the pool. Chlorine- free shock has a neutral pH and will not affect any of your other chemical levels. … And in turn, it will delay your swimmers from returning to the pool.

Does CYA reduce over time?

Because cyanuric acid stabilizes the chlorine molecules and keeps it from breaking down in the sunlight, it’s essential for anyone with an outdoor pool. It’s such a popular product because it maintains chlorine levels effectively and reduces the amount of time you have to spend maintaining proper levels in your pool.

Does cyanuric acid float or sink?

As for the “heavier than water” matter, chemgeek, cyanuric acid is heavier than water.
