Chances Are your CYA levels are low because you're not using stabilized chlorine.? Stabilized Chlorine, like dichlor granules or trichlor tablets, already contains cyanuric acid.. This helps protect the chlorine from being destroyed by the sun's UV rays.

So If you're using unstabilized chlorine, like liquid chlorine or bleach,, it won't have any CYA in it. Without Cyanuric acid,. your chlorine will quickly break down under the sun's ultraviolet rays. Your CYA Levels can also drop when your water's diluted..

So If you had to partially drain or refill your water recently,, your CYA levels could be low. Low Cyanuric acid can cause high chlorine demand or the inability to maintain chlorine levels. That means no matter how much chlorine you add to your pool,, the levels drop quickly. and low chlorine can mean algae growth.

The Ideal range for your cyanuric acid is between 30 and 50 parts per million, but it's the ratio of CYA to chlorine that's the most crucial. Your Free chlorine levels should be 7.5% of your cyanuric acid levels. So If your pool CYA levels are 40 parts per million,, you'll need to keep your free chlorine levels at three parts per million to effectively sanitize your water. But Not everyone has to worry about their CYA levels.

Indoor Pool owners don't have to worry about cyanuric acid since the chlorine isn't directly impacted by the sun's UV rays and cyanuric acid only helps stabilize chlorine so it won't work in a bromine pool. Okay, here's how to raise your cyanuric acid.. There are two ways to bring up your CYA. Add stabilize chlorine to your water, or add pure cyanuric acid, also known as chlorine stabilizer.

Before You add anything to your pool,, test your water,, then balance your pH and total alkalinity. This will help any chemicals you add later work more effectively and keep in mind that it's much harder to lower cyanuric acid levels than it is to raise them, so don't overdo it. You Can always add more stabilized chlorine or CYA later if needed. Number One,, add stabilized chlorine.

Chlorine Like dichlor, granules or trichlor, tablets are stabilized, meaning they already come with cyanuric acid. So If you've been using an unstabilized chlorine, like liquid chlorine,, switching to a stabilized form will bring up your CYA levels. If You start regularly using stabilized chlorine,, be sure to frequently test your water and keep an eye on your levels. Your CYA can increase dramatically if you're using too much stabilized chlorine in your water.

and the only way to bring down these levels is by diluting your water. Number Two,, add pure Cyanuric acid, AKA Chlorine Stabilizer. If You want more control over the amount of cyanuric acid in your water, you can add pure CYA, also known as chlorine stabilizer, directly to your pool. In General,, if you have a 10,000 gallon pool, it takes about three ounces of pool stabilizer to raise your CYA levels by 10 parts per million..

Remember That your CYA levels should be between 30 and 50 parts per million, and CYA also lingers in the water, so you usually only need to add it once or twice a year. Remember, it's easier to add more cyanuric acid than it is to lower your levels, so take things slowly. Finally, cyanuric acid is exactly that, an acid. Vinyl Liners are incredibly susceptible to CYA damage.

So If you don't add pool stabilizer correctly or your chlorine tablets start to dissolve in your pool in one place,, it could damage your pool's surfaces. And as always,, be sure to wear protective gear, like goggles and asset resistant gloves, when handling chemicals..
