The world health organization recommends an upper limit of 100 parts per million ppm of cyanuric acid in a swimming pool.
Cyanuric acid low in pool.
As long as your cyanuric acid is at a reasonable level e g.
Keep your cyanuric acid levels between 30 and 50 ppm.
Cya also known as stabilizer or conditioner in the pool industry protects chlorine from degradation from the ultraviolet uv rays of the sun.
That s just a fancy way of saying it protects your pool s chlorine from the effects of sunlight.
Cya can be very beneficial up to a point but becomes increasingly detrimental to the pool beyond that.
You have to drain the pool when the level is extremely high.
You can test these levels with most pool test strips the taylor test kit or by taking a water sample to your local swimming pool store.
Backwash or replace the pool filter if necessary.
It is able to dissolve in water and has little overall effect on ph alkalinity or hardness.
Check your cyanuric acid levels to make sure they are in the safe limits.
There s a lot of discussion around the most effective level of cyanuric acid to keep in your pool.
However for a pool owner to keep it at the correct levels to work properly you can simply add some cyanuric acid granules according to the manufacturer s instructions.
The cyanuric acid in your pool should be between 30 and 50 ppm although some find it more effective closer to 80 ppm.
The very last effort that you can do to lower cyanuric acid in the pool is to drain the water.
Cyanuric acid is used in swimming pools to lower the rate of photochemical reduction of chlorine hypochlorous acid and hypochlorite ion.
You can see what the different levels of cyanuric acid stabilizer mean in terms of the amount of chlorine you need here.
Fill the pool back with fresh water.
For example if your pool has a current cyanuric acid concentration of 80 ppm and you would like it to be 60 ppm then you would replace 25 of your pool s current water with fresh water.
We recommend keeping your cyanuric acid around 50 ppm.
Less than 100 ppm you may find it more convenient to raise free chlorine than replace water.
That being said draining and or diluting water is still the most economical way to lower cya levels in a pool.
The world health organization recommends that cyanuric acid levels don t exceed 100 ppm.
What is cya and why keep it to a minimum.
It is sold as a standalone product or can be purchased as a convenient additive to chlorine tablets.
Keep in mind that the higher your cyanuric acid levels the weaker your chlorine becomes.
Cyanuric acid technically is an acid but is dissimilar to muriatic acid which the pool industry uses to manage and adjust pool ph levels.
Levels between 30 and 50 ppm particles per million tend to work well although levels up to 80 ppm can be safe.
