brandolando4 Posted January 25, 2011 Share Posted January 25, 2011 Hello, so i was testing my water again with the api test kit and i did the steps and waited the five minutes to determine the color. It looked to be the yellow color corresponding to 0. Anyway my friend called me and i left the room for like 5 more minutes and when i came back the solution looked more green corresponding to .25 ppm. Which reading should i use?? Link to comment
seabass Posted January 25, 2011 Share Posted January 25, 2011 To me, that would indicate the lower value; however, I wouldn't consider it undetectable. Link to comment
