Adjusting Cyanuric Acid

It is recommended that dry chemicals first be mixed into a generous amount of water in increments of about two pounds, and the predissolved mixture be distributed evenly around the pool unless directed otherwise.

Precautions

Usually a 30 - 50 ppm concentration of cyanuric acid will produce good chlorine stabilization. However, your service professional may have a different recommendation. Usually cyanuric acid is added to a skimmer and travels to the filter where it may take 24-48 hours to completely dissolve. Determine how much cyanuric acid you wish to add and find this number on the left-hand side of the table. Match this with the pool or spa water volume listed at the top of the table. Keep in mind that dichlor and trichlor products will add cyanuric acid also.
