Hi all I'm working with the cyanuric acid test and it has 2 scales on the back of the tube one is cya and the other is ml i get 50 cya and the ml is about 5 what is this ml scale for? i'm starting to feel real stupid at this point because I bought strips and they indicate below 1 ppm cya I think I'm reading the tayler kit wrong. what would i be doing wrong. Taler says read comparator tube at liquid level on the back and record reading as parts pr million as i did and get 50 but checking whith strips i get less then 10 over and over. I'm not saying the strips are right but I realy think I'm missing somthing. signed Duuu
