Pool Pros text questions here Rudy dives headfirst into cyanuric acid — CYA, stabilizer, conditioner — the most misquoted, weaponized, and argued-about chemical in the pool industry. He breaks down what the science actually says about HOCl in stabilized water, why that old HOCl / OCl⁻ chart belongs in a museum, how CYA really impacts ORP, TA, and LSI, and why “chlorine lock” is less supernatural curse and more “you nuked the stabilizer and fed the biofilm.” Between the chemistry deep dive, Rudy hits the global pool-industry newswire : PHTA’s APSP-11 rewrite, bromate and sodium bromide drama, media consolidation across major trade mags, massive international trade show attendance, European trends in energy-efficient builds, Australian code delays, and South American market movement.
