Enthusiastic "Re-Beginner"
OMG! (as the high school girls seem to always be saying around here) You TOTALLY can't use the same syringe/dropper for the different purposes. Definately yet another thing we may have deemed obvious that we've been leaving out of our beginner paragraphs!
Whenever you're lost you just need to start by getting several sets (perhaps 4 sets of tests 12 hours apart, so two days worth) of tests of everything (ammonia, nitrite(NO2), nitrate(NO3), pH) and post them up here on your log and let the members take a look. If you don't have new syringes/droppers to use then be sure to take them apart and clean each part in tap water, followed by a couple of distilled water rinses. We are measuring things in the *parts per million* here, so even the slightest traces of these substances may show up as a test result - the previous use of a testing syringe for your concentrated ammonia solution would show up as quite a reading or a "messing up" of any of these tests.
