Which one should I believe In?
I have an API and every time I tested ammonia I had a hard time reading it since it was between 0ppm and .25ppm. So I bought a Hanna Checker for a more “accurate” reading and first it was reading .7ppm and today it was reading 2.0ppm while API was reading 0 to .25ppm.
Fish look fine. Do you think I got a defective one or which one should I believe in?
