Am I the only person that struggles when testing my CYA? I'm using a TF-100 kit. It says to keep filling the C.A. View Tube until you can no longer see the black dot in the bottom of the tube. Sounds easy peasy until I actually try to do it. It says to hold it at waist level, but is that just to make it easier to look down the tube? I have a hard time with glare if I hold it that far away from my eyes. Should I be unable to see the black dot regardless of where I hold the tube? If I can make out the dot at all, I need to add more solution, correct? It is easy for me to second guess myself when doing this test. And getting a second person to look at it did not help...
I am still pretty new to this, but I know that knowing my accurate CYA level is very important when balancing my chlorine. Any advice would be awesome!
