So I tested my water last night. CYA came up to be about 12. Is this is correct if I just filled my pool and have not yet add it? Or is it just a reading from the solution I added to the mix ?
I bought the LaMotter ColorQ Pro 7. I have to add a pill to the glass tube and crush it to get CYA reading. So I assume the 12 might come from the pill? Or basically the unit is faulty?What test are you using that can give you a value of 12 on the CYA test?
CYA does not naturally occur in water.
That makes sense cause I do use one. I had no idea they put CYA in the pucks. And yes this is new fresh water.It shows you have an inline chlorinator- trichlor pucks have cya - also unless u removed every drop of water before you filled there could be cya in the water.
I have done side by side testing with a Taylor K2006 and the ColorQ with the tabs. I originally got the ColorQ because I wanted an "automated eye" for the CYA test because I was having difficulty knowing if I was doing it right.I will try the tap water and probably one more time pool water with another pill. Anyone ever did a test where they compare TF-100 to ColorQ results
