Levels should be at 30 60 ppm in salt water pools and 70 80 ppm in non salt water pools.
Cyanuric acid low in pool.
Keep in mind that the higher your cyanuric acid levels the weaker your chlorine becomes.
Cya also known as stabilizer or conditioner in the pool industry protects chlorine from degradation from the ultraviolet uv rays of the sun.
It is sold as a standalone product or can be purchased as a convenient additive to chlorine tablets.
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.
The world health organization recommends that cyanuric acid levels don t exceed 100 ppm.
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.
The cyanuric acid in your pool should be between 30 and 50 ppm although some find it more effective closer to 80 ppm.
Cyanuric acid is used in swimming pools to lower the rate of photochemical reduction of chlorine hypochlorous acid and hypochlorite ion.
Fill the pool back with fresh water.
They arrived at this number based on the assumption that children will likely swallow some water while swimming and if they ingest too much cya it can make them sick.
That being said draining and or diluting water is still the most economical way to lower cya levels in a pool.
Backwash or replace the pool filter if necessary.
Cyanuric acid technically is an acid but is dissimilar to muriatic acid which the pool industry uses to manage and adjust pool ph levels.
Low cyanuric acid levels are not usually too much of a problem since even trace amounts can increase the life of your chlorine.
Keep your cyanuric acid levels between 30 and 50 ppm.
What is cya and why keep it to a minimum.
There s a lot of discussion around the most effective level of cyanuric acid to keep in your pool.
You can see what the different levels of cyanuric acid stabilizer mean in terms of the amount of chlorine you need here.
As long as your cyanuric acid is at a reasonable level e g.
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.
We recommend keeping your cyanuric acid around 50 ppm.
The world health organization recommends an upper limit of 100 parts per million ppm of cyanuric acid in a swimming pool.
Levels between 30 and 50 ppm particles per million tend to work well although levels up to 80 ppm can be safe.
That s just a fancy way of saying it protects your pool s chlorine from the effects of sunlight.
Less than 100 ppm you may find it more convenient to raise free chlorine than replace water.
Check your cyanuric acid levels to make sure they are in the safe limits.
Cya can be very beneficial up to a point but becomes increasingly detrimental to the pool beyond that.
