I've googled, searched, etc. and get differing answers to the correct way to do this. What is the general train of thought here?
Hold test tube directly against the white card background.
Hold test tube slightly away from the white background.
I've been holding mine directly against the white card and under bright flourescent lighting in my kitchen. For comparison sake I held the tube away from the card slightly to let the light shine through the water and I get a totally different reading. Example is on Nitrate test, against the card it shows around 80. Slightly away from the card it shows between 20 and 30. So.......
Thanks!
