Please note that we have not yet made a video for the new type of ammonia test. Please look at the PowerPoint, the online lesson, or the PDF document to read the instructions for the new type of ammonia test. Basically, you dip the test strip in the water sample for 5 seconds, remove with pad face up and hold level for 60 seconds. Do not shake off excess water. Then, compare the colour on the test strip to the colours on the colour chart.
