How do I lower the cyanuric acid in my pool?
How to Lower Cyanuric Acid in Your Pool
- Step 1) Drain some of the pool water (to waste).
- Step 2) Top the pool back up to normal levels.
- Step 3) Run your pump for a few hours to circulate the water and mix the fresh water in with the existing water.
- Step 4) Retest the cyanuric acid / pool stabilizer levels again.
What happens if CYA is too high?
Stalls chlorine effectiveness. High CYA will weaken your pool’s chlorine and keep it from doing its job. Referred to as chlorine lock, this happens because high CYA overpowers the free chlorine level in the pool. With compromised chlorine you’ll soon start seeing issues like algae and cloudy water.
Can you swim in a pool with high cyanuric acid?
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.
Does CYA reduce over time?
Yes, entirely possible. As you point out, there is a testing variance to consider and CYA will naturally degrade a few ppm per month, maybe a little more.
Does shock raise cyanuric acid?
Cyanuric acid is also known as a Stabilizer, it helps the chlorine stay in your water. When you “shock” continuously what you’re doing is you are actually increasing the Cyanuric acid levels steadily but the chlorine levels go up fight off what they need to then they come right back down.
Does Rain lower cyanuric acid?
Cyanuric acid does not deplete on its own, but the level will be reduced slightly with the addition of heavy rains, which of course, contains no cyanuric acid stabilizer. If your cyanuric acid levels are rising above 50 ppm, you can be glad that heavy rain will dilute the levels of CYA in the pool.
Does evaporation lower CYA?
1) No, unfortunately CYA doesn’t go down with evaporation. You will need to drain/replace some water.
What causes CYA to drop?
When bacteria get going consuming CYA, it tends to happen fairly quickly. In addition to water dilution, CYA can also drop by being slowly oxidized by chlorine, but that usually takes months to notice. It’s possible that some chemicals in the water may make that reaction more rapid, but we don’t know for sure.
Does bioactive CYA reducer work?
Bottom line is that the product does work, although I couldn’t duplicate the manufacturers numbers all the pools experienced a drop in the Cyanuric Acid levels. Adding the product will be less expensive in most cases then draining the pool down and if you need to add two 8 oz.
What happens if cyanuric acid in pool is too high?
When cyanuric acid levels get too high, it can cause something referred to as chlorine lock, which basically means your chlorine has been rendered useless. You’ll know it has happened when your chlorine test shows very or little chlorine even right after you’ve added it to the pool.
Is there a way to lower CYA levels in a pool?
There unfortunately is not many options for chemically reducing CYA levels in your pool. So depending on the size and location of your pool, the most common and practical way is dilution. Having said that, we’ll go over both of those options in this article. How to lower cyanuric acid (CYA) in a swimming pool? The only sure method is dilution.
What does CYA stand for in pool water?
High levels of Cyanuric Acid (CYA) in pool water can cause issues. That’s why Minimal CYA is Orenda’s Fourth Pillar of Proactive Pool Care.
What to do if your pool has too much cyanuric acid?
After using any of the above methods and retesting the pool, you may realize you’ve taken out too much cyanuric acid. If your CYA level is below 30 ppm, you can raise the amount of cyanuric acid by using stabilized chlorine, or by simply adding cyanuric acid (usually found as pool stabilizer or pool conditioner).
What should the pH be in a cya reducer?
The day before (and day of) using a CYA reducer, the pool has to be at least 65°F. Also, you’ll need to test the water to ensure the chlorine is between 1 and 5 ppm, the pH between 7.2 and 7.6, and total alkalinity between 80 and 120 ppm.
