How To Do A Water Test

[SHAKEEL]

ok so a lfs said that i was doing my water test wrong you know those test with the color chart card to determine how the water is he told me instead of hold the test tube beside the color bars that i should hold it right in front of them and the color bar that you cant or becomes invisible is that tests ppm what do yal think and how do you do your tests.

I am confused at what kind of water test you are doing
Phosphates, nitrates or ammonia?
Is this test on the display tank water or ro/di water.

lets say i perform a nitrate and phosphate tests and when i hold the test tube up to that color card for results do i hold it in front of the color bars or beside them.

both are good methods but make sure you are holding them up in natural sunlight as in a window. Floreescent lighting can really make a difference on the colour tests.

I like to hold mine in front of the colour chart. I look for the two colours to appear as one and then I know the colours are the same.

thats what the guy was telling me a the lfs hold in front of the color bars to get a better test not beside.
