Re: How did the CYA levels get so high in my pool ?
Thank you so much!! So glad I found this site.
I've been fighting algae all summer - I'd test the water - chlorine and PH were fine. Then I splurged and bought a test kit with CYA test in it. Found the problem... CYA was over 100!! And I had been using the tablets for the last year. No wonder pool was great last year and such a pain this year. While I'm not thrilled to have to replace the water to get the levels normal... its much cheaper than a new filter, which is what I swore I needed ( I hate it when hubby is right!!) thanks again!!
