Cyanuric acid is used in pools as chlorine stabilizer. The problem with CYA is that when concentration gets too high it reduces efficiency of chlorine. The target range is 30ppm-50ppm. There does not seem to be any commercially available additives to reduce concentration of CYA.The most commonly suggested method is dilution, which requires large amount of water for a decent size pool. My question is: are there chemicals, that would be safe to add to the pool to reduce CYA concentration and say complex and precipitate it to be filtered out by pool filter? Wikipedia states that it has strong interaction with melamine, forming insoluble solid. Would this be a safe route to reduce CYA concentration in pool? It should be noted that Sodium bicarb, chlorine, and sodium sulfate are usually also present in pool water as alkalinity and pH stabilizers.
