What causes high cyanuric acid in pool?

It seems like stabilized chlorine use is the main reason for high levels of CYA. As water evaporates, CYA stays behind, just like calcium and salt. If you are using a stabilized chlorine like trichlor or dichlor, CYA accumulates…fast. One pound of trichlor in 10,000 gallons of water will add 6 ppm of CYA.

What is the correct level of cyanuric acid in a pool?

CYANURIC ACID

The recommended level is 20-50 ppm; levels over 100 ppm will not be accepted. If levels rise above this point, a portion of the pool water must be removed and fresh water added; there are no other means of diminishing the cyanuric acid in a pool.

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.
