I thought of an idea that has helped me to read the results more accurately.
If you are not sure how blue your result is, get another test vile and fill
it with clean water. Then look at both of them on the card at the same
time. This can help give you an idea of how blue your reading actually is.

Hi all,
I am having trouble deciphering the reading this test kit is showing
me.
Maybe I am getting old but if you look at the card, it can be hard to tell
the difference between two shades like .25 and .5

I mean, yeah, I CAN see a difference but it is SO minute.

Anyway, are there any tips for getting a match between your test vial and
the card? Like, if you put the vial on top of the card but have it on
BOTH
the white and the blue, can you get an idea of where you are?
For example, if I compare the color of my liquid to say .03, I can clearly
see the blue for .03 is darker than my vial when looking through the
liquid
from above. But if I have the vial over the WHITE only, it appears to be
about .25

Another question, Take Saliferts calcium tesk kit for example. I think
that is called a "tritation" method? Where you slowly add a third
component
until the media turns to a different color and THAT is your reading
result...

Does anyone know of a test kit like that for Phosphates?


TIA
