So I made a post a while ago about a reading of point .25ppm of Ammonia in my 29 gallon. I've been more detailed check of my old 20g and my new 55. They all have the same color reading of .25ppm.
In my 55g I would not be as surprised if it spike, it is fairly new. However, I have had Kuhli loachs in the 20 for almost two years. I feel like if it spiked randomly or have been high they would have died already. I have not added new fish to that tank since Feb. The only thing I have added was some live plants. I have not lost a fish since I added the new ones in Feb.
I only use distilled water, from Walmart, for my tanks.
Could it be a false test? The results haven't changed after multiple WCs of 4 gallons. (I don't dare do more, because of the live shrimp and snails in the tank)
NO3: 30 (Added plants to help lower this, as well as larger water changes.)
