Your last values sit in the fields as a starting point. A field you leave blank stays blank. It is never recorded as zero, because "I did not test that" and "it was zero" are not the same thing, and a log that confuses them is worse than no log. Colour kits need a wait between the reagent and the reading, and a different one for each test. Start a timer per parameter and run three at once without losing track of which is ready. A nitrate read early is a number that goes into the log and stays wrong. AMMONIA, WORKED OUT PROPERLY The number your test kit gives you is total ammonia. That is not the part that harms fish. Free NH3 is, and how much of the total is free depends on pH and temperature. Aquarium computes it from…
