I'm cycling my tank (fishless) and at the point where I am testing nitrates, and I am getting varied results even a few minutes apart. For example, today I tested it at it looked like it was at 30, meanwhile my ammonia had dropped to .5 overnight so I added more ammonia, and then tested nitrate again because the 30 seemed lower from when I last tested it. well nitrate was now even lower, has this happened to anyone else? Is it possible that testing nitrate not long after adding pure ammonia will alter the results? Should get a new nitrate test kit? It's the API test and expires in 2017..
