I have a procedural question regarding this test kit. I noticed that the copper test indicates that the cap should be removed and "to view the color of the solution by looking down from above (through tube from top to bottom)". However, the Saltwater Master kit (ph, amonia, nitrite, and nitrate) does not indicate to do this. Therefore, what is the most accurate way to view these tests: through the side or from above? I don't see why someone can't create a test kit that resembles a pregnancy test: blue means ph of 8.0, pink means 8.1 and so on.
