I bought my house over a year ago, first time pool owner, and right after was told to drain the pool since CYA was very high and chlorine was locked low and it would not change not matter how much I shocked.
Bye the end of the summer the CYA was again extremely high and I was having huge fights with Algae. Now the Algae are starting to form again since water temperature is starting to increase – I am in Texas. CYA is still very high.
Do I need to drain again? This seems very frustrating and expensive to do it every year.
My pool is 21,000 gallons and I use mostly Leslie’s products:
3" Chlorine Tabs
Shock: Started with Chlor Brite but switched to Power Powder Pro to see if it would help but it didn't make a difference
I also tried using Phos Free last year but it didn't seem to help. Every time I got Algae I treated with a ton of Shock and Green to Clean and it would go away but come back after 2 weeks.
Thanks a lot! I really appreciate your input!
