So, for 25ppm, the sanitizer should be 1.5ppm, for 50ppm it should be 3ppm.įor every 30 ppm it needs to be raised, add 4lbs per 10,000 gallons.

The free chlorine levels should be regularly tested and remain around 7.5% of the cya level. However, keeping your cya below 50ppm isn’t enough. Between 20ppm to 50ppm is often considered enough. This could impact the effectiveness of the chlorine which is why it is better to stay below. If these studies are to be followed then anything above 50ppm is going to be useless. Add too much, and there is research that suggests it becomes ineffective. This depends on a few factors, with plenty who disagree on how much is necessary for different sized pools. Without Cyanuric Acid, expect to be adding a lot of chlorine, only for it to need topping up soon after. This is why it is called a stabilizer, it helps to keep the chlorine levels under control. However, it has a weak nitrogen bond which means it can still break from the CYA to kill bacteria and other nasties. It binds to the chlorine, protecting it from the sun’s rays. Although regular maintenance will help a pool owner keep an eye on the chemical balance, it can be frustrating having to throw so much chlorine into the water every couple of days. Before too long, the water is unsafe to use and a breeding ground for bacteria and algae. This means that when it is being used the most, the chlorine levels are almost constantly dropping. In peak summer, UV rays can evaporate over 50% of the chlorine in a pool within a couple of hours. This will not only ensure you are putting less chlorine into the pool, but also make it safer for everyone to use. It helps to prevent the UV rays from evaporating chlorine so much. Where does cya come into this? Well, its benefit lies in how it protects chlorine levels. UV rays cause chlorine to evaporate which is why it is important to clean a pool and stay on top of the chemical levels regularly, often twice weekly in high season. The UV rays may be welcomed by many after months of cold, but in terms of the pool’s chlorine, it is a nightmare. Why Do People Use CYA?īecause the summer months play havoc with the chemical levels. It can be purchased in granular and liquid form so whichever is most convenient for you. Every pool cleaner service will have it in the back of their truck, ready to go, and anyone cleaning their own pool should have some to hand. Sometimes known as a pool stabilizer or pool conditioner, it is one of the most common and significant pool chemicals.
Not only are we going to understand it better, but see when it is useful, and see if you really need to use this common stabilizer or not. But what is it used for, and why? Any responsible pool owner needs to get to know the chemicals and what they can be used for which is why we are going to take an in-depth look at this useful chemical. In terms of pool care and maintenance, a lot of people ask what does cya mean? The short answer is that it stands for Cyanuric Acid.
