Reading water tests

OK, here's what I did to kinda see where you were coming from. I added
light as you said and that washes out my sample in the tube. MY method
(ymmv) is to hold the tube 1/2'' away and yet parallel to the card,
this gives accurate reading for me every time.

That's all I got :-) Good Luck

I'll give it a shot, thanks

Should water tests be read with a light shining through it, and held up
against the white part of the card, or in shadow, held up against the
white
part of the card?

What do the instructions in your test kit specify?

I was taught in school to use a white background with a lot of light to
pick up the color of the solution for liquid tests.

I do not think there is much, as long as the same amount to who was hit by testing the color gradient. For me, I have been testing do not add any light will cast a heavy shadow, and test before any changes of water.
