Cyansyra pool
Cyanuric acid —also called CYA, pool stabilizer, or pool conditioner—is a weak acid that protects your chlorine from the sun’s ultraviolet rays, allowing it to work for much longer periods without constant top-ups. The ideal range for cyanuric acid in your pool is between 30 and 50 ppm (parts per million). The number one thing that keeps people from having a pool beyond cost is keeping the chemicals balanced. Cyanuric acid CYA is one of the most important pool chemicals.
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. As you well know, chlorine is essential to the hygiene of your pool. Coli bath.
The Truth About CYA in Pool Water: Everything You Need to Know
Without getting into too much of the chemistry, cyanuric acid CYA works on the molecular level by attaching to 3 chlorine atoms the free chlorine through a weak nitrogen-chlorine bond. However, the weak nitrogen bond allows the chlorine to let go when it needs to kill bacteria and other pathogens. We select, test, review and suggest the best products.

Depending on who you ask, you may get answers from 10 to ppm. So, if you can keep your CYA at or below 50 ppm, that should provide plenty of sunscreen protection for your chlorine. The actual amount you add to the pool will depend on the volume of water and amount of chlorine in your pool. Once you put it in, it stays at pretty much the same level unless you have to do a water change or have a big splashout or a lot of evaporation.
Any dilution as a result of adding water, even from rain, will lower the CYA concentration. CYA is a pretty strong acid on its own, so the best way to add it is to dissolve it in a bucket of warm water. Then go all around and pour the solution just inside the edges of the pool. You can often add CYA solution or even undiluted CYA to the skimmer which will allow the pool pump to do all the mixing. Luke Reed Expert Tip. There are a couple ways to test the CYA.
One is via a complete pool testing kit , in which you can test all the essential pool chemicals. Look on the ingredient label. If you make the switch and find CYA is still a bit too high, allow some splashout and evaporation, then top off your pool with fresh water to dilute the CYA levels. If CYA is very high, you may need to actually drain your pool and refill it. But always test the CYA after a refill before you add any more.
This is because CYA can linger in the pool filter system as well as the plaster and calcium scale.
However, other experts disagree, saying that at least a small amount of CYA is good for indoor pools, especially those that may be surrounded by windows that let in a lot of sunlight. It can also tame the degrading effects of chlorine on hair, skin, and swimwear. If you have young kids or lots of little kid guests in the pool, keep the CYA levels to a minimum. Pool company puts Cyanuric acid granules into skimmer basket and they clog one pvc pipe that is closed off.
Skimmer has 2 pvc pipes one to pump and one closed off to main drain…will the granules harm the pvc pipe if it sits in there for a week or so before it slowly breaks down? I have a gallon in ground pool. My cy acid continues to run It keeps pool light green and cloudy. Keep taking our 2 feet then adding fresh water back. Very little change. How do I refute the cy to 50? My cyanuric level went from 30 to in one week.
Is that possible or a misread? How does that happen?

I have an above ground with gallons. How much longer should I daily drain? All other chems are good. Anything over 50 and your chlorine binds, no free corrode to sanitize. Cyanuric acid barely affects the pH levels of your pool.
