  • The Free Chlorine and Cyanuric Acid Relationship
    Stabilizer (Cyanuric Acid or CYA) CYA protects your free chlorine (FC) from the sun, reducing the amount of chlorine you need to add daily Too much CYA (more than about ~90 ppm), and it becomes difficult to maintain disinfecting FC levels
  • CYA - Further Reading - Trouble Free Pool
    Cyanuric acid and the related chlorinated cyanurates protect chlorine from degradation or loss due to UV light Chlorine degrades when exposed to UV light When chlorine in water is exposed to UV light from the sun, the hypochlorite ion (OCl-) and hypochlorous acid (HOCl) both react with UV light and get degraded into oxygen gas and chloride ion
  • cyanuric acid vs Isocyanuric acid | Trouble Free Pool
    Cyanuric acid is the enol tautomer of isocyanuric acid It has a role as a xenobiotic It is a member of 1,3,5-triazines and a heteroaryl hydroxy compound It is a tautomer of an isocyanuric acid and… Tautomers are isomers of a molecule that exist in solution or in a cell They are interchangeable forms because chemical bonds are rearranged
  • Cost Comparison of Cyanuric Acid (CYA) Sources
    For the amounts as indicated above, pure Cyanuric Acid needs 0 35 ounces weight of Lye, Trichlor needs 1 6 ounces while Dichlor needs 0 77 ounces, so this adds $0 07 to the Cyanuric Acid price, $0 30 to the Trichlor price and $0 14 to the Dichlor price So this is less expensive than Borax, but more expensive than Super Washing Soda
  • Using Caustic Soda to neutralize Cyanuric Acid
    I have a small 3,000 gal pool and use chlorine tablets which of course contain cyanuric acid Since I use a 200 g tablet every 5-7 days, my pH constantly drops, but I have worked out that I can maintain a good pH of 7 5 by adding about 30 g of caution soda (NaOH) to neutralize the cyanuric
  • Cyanuric Acid Location: Top, Bottom, or Everywhere?
    For something like Cyanuric Acid, then it might be somewhat higher, but even substances that have concentration ratios of 243 at ocean depth (e g for maltose), still have less than 0 1% concentration ratio in 1 meter depth We really need to squash this idea of denser soluble substances somehow measurably concentrating at depths in pools
  • Acid - Further Reading - Trouble Free Pool
    Cyanuric Acid See CYA Phosphonic Acid Phosphonic acid is used as a sequestrant Nitric Acid In some areas of the world, Muriatic Acid is unavailable, and Nitric Acid is used instead Do not use nitric acid, it is too dangerous outside of a fume hood Nitric acid is dangerous to the skin and other organic tissues
  • Cyanuric Acid and Alkalinity. | Trouble Free Pool
    Cyanuric Acid and Alkalinity I'm not sure if this has been posted elsewhere and I've read quite a few posts but not seen it mentioned I read a paper some time ago regarding the Total Alkalinity and Cyanuric Acid It stated you must use a correction factor to correctly ascertain your correct alkalinity level when taking an Alkalinity reading
  • Bioactive and cyanuric acid loss or degradation over winter
    There is oxidation reaction of Cyanuric Acid by Hypochlorite Ion described by John A Wojtowicz in the Journal of the Swimming Pool and Spa Industry (JSPSI) Volume 4, Number 2, pp 23-28 (2001) reprinted in "The Chemistry and Treatment of Swimming Pool and Spa Water" in Chapter 5 3 "Oxidation of Cyanuric Acid with Hypochlorite"
  • Bio Active Cyanuric Acid reducer review - my results so far
    Leslie tested my Cyanuric acid 3x, first time they said 100, second time i said i got much higher results to which they stated their equipment can't test above 100, and last results was wrong the following 2 tests they did dilution of 1:2 their results were then 120 then 140 i don't trust these numbers
