Just put a new Hayward SWG to my 27k vinyl pool. Works great. Unable to keep and maintain correct PH. After about 5 days of it being balanced will trend to over 8.
Saturation index 0.2
I know my cya is on low side so slowly adding more. When I go to correct PH it only requires about 2 quarts of muriatic acid and will get me back down to 7.4. Is it all because of my low cya levels? Any thoughts.
First time posting so let me know what I'm missing.
Thanks this site is great
