What has cyanuric acid?

Author: Miss Aylin Cartwright PhD  |  Last update: Sunday, June 19, 2022

Cyanuric acid (CYA) is one of the most important pool chemicals. You've probably heard it called “pool stabilizer” or “pool conditioner”. It comes in either liquid or granular form, but often is mixed in with chlorine tablets or sticks (also called trichlor) and in chlorine shock (called dichlor).

What chemicals contain cyanuric acid?

Cyanuric acid is available as a granular solid and as a liquid (sodium cyanurate). Most commonly, however, cyanuric acid is found in stabilized chlorines dichlor and trichlor. These stabilized chlorines have about 50-58% CYA in their formulas.

How do you raise cyanuric acid?

Cyanuric acid is raised by adding chlorine stabilizer containing cyanuric acid. The only way to lower cyanuric acid is by replacing water.

How do you increase cyanuric acid naturally?

How to Raise Cyanuric Acid in Pool
  1. Step 1) Calculate the volume of water in your pool.
  2. Step 2) Calculate the amount of cyanuric acid (stabilizer) you will need.
  3. Step 3) Add the Cyanuric Acid.
  4. Step 4) Turn your pump on to the “circulate” or “filter” setting.
  5. Step 5) Retest the water and repeat if necessary.

Is baking soda the same as cyanuric acid?

Baking Soda is used for raising the total alkalinity of the pool, which is the key to keeping the ph in balance. It's not a stabilizer. That's cyanuric acid.

WHAT IS CYANURIC ACID

Does tap water contain cyanuric acid?

Cyanuric acid is present in drinking water when chemicals commonly referred to as dichlor (anhydrous sodium dichloroisocyanurate or sodium dichloroisocyanurate dihydrate) or trichlor (trichloroisocyanuric acid) are used as alternative free chlorine sources.

Does baking soda raise cyanuric acid?

Baking soda is the best way to raise total alkalinity with minimal effect to pH and cyanuric acid.

Does pool shock raise cyanuric acid?

2. Dichloroisocyanuric Acid: Also known as “dichlor,” this is another type of chlorine shock. Dichlor contains both chlorine and cyanuric acid and will, over time, raise your cyanuric acid levels.

Does a saltwater pool need cyanuric acid?

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.

Is muriatic acid the same as cyanuric acid?

Yes both cyanuric acid and muriatic acid are both acids but they serve different purposes for the pool owner. Cyanuric acid has the chemical formula CNOH, whereas muriatic acid is a diluted form of hydrochloric acid, HCI.

Does baking soda lower cyanuric acid?

No, cyanuric acid and baking soda work in very different ways in your pool. Baking soda raises the total alkalinity in your pool. But baking soda does not protect or stabilize your chlorine, like CYA.

Do I need cyanuric acid in my pool?

Areas exposed to high levels of sunlight should maintain 60 – 80 ppm (parts per million). Pools using an ORP Controller (Oxidation Reduction Potential) such as the AutoPilot Total Control, should maintain 30-50 ppm. Indoor pools do not need cyanuric acid, unless it gets periodic exposure to sunlight.

What does cyanuric acid do for a pool?

Cyanuric Acid (CYA) is a pool balancing product used to help chlorine last longer. Chlorine, in its natural form, is unstabilized—which means it degrades when exposed to sunlight. Adding Cyanuric Acid reduces the sun's impact on chlorine loss.

Does pool chlorine contain cyanuric acid?

Dichlor and trichlor contain both chlorine and cyanuric acid so it is not necessary to add cyanuric acid to the pool water. Stabilizer (aka cyanuric acid) is also sold at most pool supply stores. Cal-hypo and liquid chlorine do not contain stabilizer.

Does Clorox pool shock have cyanuric acid in it?

Clorox has absolutely NO Cyanuric Acid (CYA) in it nor does it increase CYA at all when you use it. You should show them. It's mostly water, then sodium hypochlorite (i.e. chlorine), and sodium chloride salt, and then a small amount of sodium hydroxide and a very small amount of sodium polyacrylate.

What is cyanuric acid in a hot tub?

Cyanuric acid (CYA), also called stabilizer or conditioner, is used in pools and spas exposed to the sun to reduce the rate of decomposition of available chlorine by ultraviolet rays in sunlight. Stabilized forms of chlorine, such as dichlor and trichlor, contain CYA in their formulas.

What is dichlor for pools?

Dichlor, short for Dichloro-S- Triazinetrione, is one type of chlorine available for keeping pool water clean. Similar to trichlor, a different kind of chlorine, dichlor is usually granular but can also be found in tablets. You can buy dichlor in one-pound bags or in bulk.

Does dichlor contain cyanuric acid?

Dichlor by weight contains 57% cyanuric acid; trichlor contains 54% cyanuric acid.

Will low cyanuric acid make pool cloudy?

Answer: Cyanuric acid shouldn't be at Zero for an outdoor swimming pool because chlorine will deplete faster in hot and humid weather, leading to cloudy water. If your FC is at normal level of 3ppm, raise Cyanuric acid level to 40 ppm and you will reduce chloramine levels that make your water appear cloudy.

How do I raise the cyanuric acid in my saltwater pool?

Use test kits or strips designed to measure cyanuric acid, so you can determine how much acid to add to your pool. To significantly raise levels, dissolve powdered cyanuric acid or add a liquid version. You can also add stabilized chlorine for regular maintenance.

Is low cyanuric acid bad?

Recent CDC research presented at the October 2015 World Aquatic Health Conference demonstrates that even at cyanuric acid levels as low as 10 to 20 ppm, the current recommended remediation protocol is not adequate to inactivate the necessary 99.9 percent of Crypto in pool water.

Is cyanuric acid hazardous?

Uses Advised Against: None identified. OSHA REGULATORY STATUS: This material is not considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200).

Can you use baking soda as pool stabilizer?

When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.

What is swimming pool acid?

Hydrochloric acid is a very common substance that's also known as muriatic acid. When you mix water with hydrogen chloride, the end result is hydrochloric acid, which is a corrosive substance that has many different applications to it.

What is in pool stabilizer?

They are derived from a chemical compound called cyanuric acid (CYA), and come in several forms—granular or liquid, or in chlorine tablets (or sticks) called trichlor, or shock, called dichlor. When chlorine and cyanuric acid are combined in shock or tablet form, it is referred to as stabilized chlorine.
