Hey folks, I just got a new vinyl pool liner and filled the pool up with tap water (city water). It filled up last night and I performed the first test just now (next afternoon). Everything looks good except for the CYA.
When I mix the pool water with the R-0013, wait 30 seconds, mix and then pour into the tube, the mixed sample is perfectly clear. There is no amount that I can pour in there to make the black dot fade out. This would mean that my CYA levels are through the roof right?
The R-0013 reagent is only 3 years old (or so) so I'm not sure that it's gone bad. Surely the water from the city should have 0 CYA right?
Thanks in advance for any help!
