Summarize the key points of the article without repeating it.
Do you have a swimming pool but the water has become cloudy, and you’re concerned that the cyanuric acid (CYA) may be too high? High levels of cyanuric acid can be stressful and lead to further problems in the pool, so it’s important to get it back in balance. In this article, you’ll learn how to lower cyanuric acid levels in a pool so that you can keep it looking crystal clear.
1. Reasons for High CYA Levels
CYA Presence in Water
Cyanuric acid is present in all swimming pool water. Most municipal water suppliers add it to the water to protect against UV rays from the sun. It helps to prevent chlorine from evaporating quickly out of the water. If a pool has a cover, the CYA levels will naturally decrease a bit by itself.
Adding High Concentrations of CYA
Another reason for high CYA levels is from adding too much of it into the water. Some pool chemicals, such as shock, contain high concentrations that can cause CYA levels to remain elevated.
Failure to Test Regularly
When not tested regularly, it’s difficult to detect and balance the control of the swimming pool’s water chemistry. As a result, the levels of cyanuric acid can reach a high point in the water and cause problems.
2. Benefits of Keeping Low CYA Levels
When the CYA levels are in a proper range, scale buildup will be prevented. Scale is caused when calcium comes into contact with cyanuric acid. The acid will draw calcium from the water, causing scale buildup on the walls, filter, and plumbing of the pool.
Increases Chlorine Efficiency
A low level of cyanuric acid also increases the efficiency of chlorine. This means that less chlorine is needed to achieve disinfection of the pool. The chlorine is not as bound up by CYA allowing it to be free to destroy bacteria and algae.
High levels of CYA put stress on the chlorine, causing it to break down quicker. When combined with a UV filter, it can increase the chlorine break down 10x faster. Constant testing of water chemistry is the key to knowing when it is out of balance and needs attention.
3. Lowering CYA Levels
Draining and Partial Replenishment
Draining and partial replenishment is a good method for controlling CYA levels. It will require the pool to be drained down to below the skimmer. It is important to use a low CYA (usually lower than 30 ppm on most municipal water sources) water to filled the pool back up.
Using Advanced Pool Products
Advanced pool products such as chemi-crystal ultra can and will help reduce the levels of CYA. It is a mineral-based algaecide and clarifier that helps reduce the need for chlorine shock. It’s easy to use and can also help reduce the levels of CYA in a pool.
Aquachem is another option for lowering the levels of CYA in a pool. It is a great product for those who are looking for an easy way to get their pool back in balance. Aquachem is used by professionals, and it’s very effective at reducing the levels of CYA in a pool.
People Also Ask
Can you lower CYA without draining the pool?
Yes, you can lower CYA without draining the pool. You can use pool products like Chemi-Clear Ultra, Advanced Pool Products, and Aquachem to help reduce the cyanuric acid levels in the water.
How often should I test the CYA levels?
It’s recommended to test the CYA levels once a week. This will help keep the levels in balance.
What is the ideal level of CYA in a pool?
The ideal level of CYA in a pool is 30-50 ppm. Anything above 50 ppm is considered to be too high.
What is the difference between chlorine and cyanuric acid?
Chlorine is a chemical used to sanitize and disinfect the pool water. Cyanuric acid is a stabilizer used to reduce chlorine loss due to sunlight exposure.
What happens if CYA levels are too low?
If the CYA levels are too low, the pool water will be more susceptible to being contaminated by algae and bacteria. The chlorine will also evaporate more quickly due to the lack of stabilization.
Maintaining proper levels of cyanuric acid is important for keeping your pool clean and healthy. High levels of cyanuric acid can cause further problems so it’s important to keep it in balance. There are a few ways to lower the levels of CYA in a pool, such as draining and partial replenishment, using advanced pool products, or using Aquachem. If you have high CYA levels, following the steps outlined in this article will help you get it back to its ideal level.
