I was wondering if there is another method to lower the CYA? My water is expensive and I dont want to have to drain all that water! My current readings are: FC 5, CC .5, pH 7.6, CYA 100, TA 120.
I have a 30000 gal vinyl inground, 24 sqft Hayward DE filter, 1.5 HP hayward single speed pump, Raytec gas heater, Polaris 280 cleaner, Taylor 2006 test kit and use bleach (lots of it it seems)
Thanks in advance for your help!
