I posted my first thread here with my test results.
On Sunday, I took my sample to Leslies for water test. Everything was close to my test values, except CYA came at 100 (my test showed 140), and phosphates were at 1000. I had removed the chlorine pellets after my test (following advice here, but I am not sure if removing those could have lowered CYA within a week so much). Leslie's recommended draining 20-30% pool, and then retesting it. Do I need to worry about that high phosphate level? Same advice as I got on in this awesome forum
I have not drained the pool yet. I talked with my pool service guy yesterday, and told him about high CYA levels. He said that CYA is a conditioner and you want it in the pool. Also, that chlorine pellets are adding that CYA, and you need it during swimming season. He said that when swimming season ends, then he switches to liquid chlorine as that does not add CYA. Is he right? He said that he wouldn't recommend draining the pool to lower CYA at this time, but at the end of the season, he definitely recommends that. What do the experts here recommend I do?
Also, the pool guy said that my pool has approximately 20,000 gallons of water..I cant believe that I am off by so much..but with his experience kind of want to believe him.
Can someone tell me how to calculate pool volume? I have kidney shaped pool..take length x average width x average depth (shallow and deep end) x WHAT??? May be this factor is putting me off. What units do I need my length depth measurements to calculate the pool volume?
