How To Lower CYA In a Pool

From https://www.swimmingpoolsteve.com/pag... this video talks about CYA (Cyanuric acid) in swimming pool water and the different available methods to reduce your CYA levels. When stabilizer levels build up too high in swimming pool water the chlorine is not able to function the same as before. This is why you are supposed to increase free chlorine levels in conjunction with the CYA levels, either 5% or 7.5% depending on who you ask. For example is a pool with 100 CYA which is higher than the 30 to 50ppm recommended range. In order to keep the pool chemically managed you would need between 5ppm and 7.5ppm of free chlorine (5% to 7.5% of CYA level) in order for their to be enough free chlorine available to keep the pool clean. Draining and refilling with fresh water is the best and most reliable method to reducing CYA levels in swimming pools. Enzyme CYA reducer is not very effective, and mobile reverse osmosis truck service is quite expensive. This is why setting your CYA at 30 to 50ppm and then switching to a NON stabilized form of chlorine treatment is best. #poolchemistry #swimmingpoolsteve #poolwater
