So until recently I have been using the tetra 5 in 1 strips to test nitrate, nitrite, gh, kh, and ph. The 5 in 1 doesn't test for ammonia so I had purchased a separate ammonia test strip kit (jungle). After my tanks finished cycling, I was consistently getting a 0ppm result on the ammonia test with the strips in both tanks. When my 5 in 1 strips ran out last week, I went out and bought the api liquid master test kit on the recommendation of others from Fishlore But the ammonia result from the liquid kit looks like it's saying .25ppm in both tanks. I tested my tap water and got the same result. Is it possible that there's ammonia in my tap water that the strips didn't pick up on? Or am I reading this wrong? Picture attached.
