There was a question in one of the Threads about reading test results and I got curious because of he different the results in ppm could be depending on how you looked at the tube so I wrote to the manufacture of the API kit and here is the reply:
"Thyra to obtain accurate results with the test kit you will want to hold the tube directly against the white background and look through the tube and compare to the colors on the chart. We only have one test kit, copper, in which you need to look down the test tube from the top to determine your reading.
If you have any other questions or wish to discuss this further, please email back or give us a call at 1-800-847-0659.

Just thought others might like to know.
