Ammonia surfactant is indicated by bubbles forming in the bottle and lasting for a few seconds when shaken. They are bad and may cause problems later on.
Pouring ammonia directly on a testing strip or directly on a vial won't give a good result as the result will be way off the scale of measurement. A 10% ammonia solution has 100,000 ppm
ammonia and you test is designed for around .1 to 10 ppm
. Probably won't work. Just test the tank water.
Many brand new tanks go cloudy during cycle. Part of that is from the smallest particles of substrate being stirred. As bacteria build n the sand bed those particles will stick together and stop floating.
