PB said I should take it in once a month or so to have them test. I did just that yesterday and they were way off in some areas.
Said FC was 6. I tested it at 2 earlier in the morning and did not add any chlorine.
Also said CYA was 60. My tests show 35 - 40
Other numbers seemed fairly inline with what I get.
I am inclined to believe my tests as I am careful and thorough when I test. They had a lot of people lined up and were splashing this and that around.
Only thing they recommended was a phosphate treatment. Not even sure what that is, but the funny thing they said was "With phosphates that high, the only thing keeping you from getting algae is the FC." Isn't that always the case?
