The ratio of free chlorine to CYA (FC:CYA) is more significant than pH in terms of attaining the desired concentration of HOCl required to kill pathogens and algae. Based on (1) and (2) above, maintaining minimal CYA is more important for chlorine …

2019年7月23日 · The table shows that people are 357 times more likely to get ill from Giardia if no chlorine is present, compared to 1 ppm FC. If 10 ppm CYA is used with 1 ppm FC, people are three times as likely to get ill from Giardia, and if 100 ppm CYA is used, people are about 17 times more likely to get ill.

chlorine combines with CYA to form new chemicals that are essentially not disinfectants nor oxidizers (to be demonstrated later in this paper). CYA has a moderately strong affinity for chlorine such that when CYA >> FC (when both are measured in their respective

2025年2月26日 · Maintaining the proper balance of free chlorine and cyanuric acid in your pool is critical for keeping your pool water sanitary and minimizing the cost of chlorine. Use our FC / CYA calculator below to determine your pool’s ideal CYA and free chlorine levels so you can keep your water safe and clear all season long using minimal chlorine.

2017年6月20日 · The following table summarizes the CYA contributions from dichloro-striazinetrione (dichlor) and trichloro-s-triazinetrione (trichlor). Dosage and application require-ments will be explained on each product label.

Two of the most important factors are UV rays from sunlight and cyanuric acid (CYA), commonly referred to as stabilizer. In this article, we dive into the relationship between chlorine and cyanuric acid, and how it stabilizes the amount of free chlorine required for your pool.

2023年6月13日 · CYA levels can be reliably measured down to 30 ppm CYA by the recommended test kits, so that's a limitation of Trouble Free Pool Care. It's minor because 30 ppm CYA has enough benefits that's it's also useful for indoor pools. So the SLAM is designed to work as part of TFPC which is in the reliable (enough) testing range of 30 ppm to 80 ppm CYA.

2024年12月13日 · Cyanuric Acid (CYA) is a chemical used in pool water to stabilize chlorine and protect it from being degraded by sunlight (UV rays). It’s often referred to as a “chlorine stabilizer” or “conditioner.” Pool conditioners are made up of cyanuric acid, but the exact forms and concentrations may vary with different conditioners.

To RAISE CH: See Treatment Tables for adjustment or go to website. To LOWER CH: Partially drain and refill with fresh water of lower hardness. Cyanuric Acid (CYA) Test

Cyanuric Acid (CYA) Test 1. Rinse and fill bottle (#9191) to 7 mL mark with water to be tested. 2. Add R-0013 to 14 mL mark. Cap and mix for 30 seconds. 3. Slowly transfer cloudy solution to small comparator tube until black dot on bottom just disappears when viewed from top. 4. Read tube at liquid level on back of comparator block. Record
