Just bought the new Hanna HR nitrate kit. It tested to 72 ppm which is alarming but the API tester says 0 (The light yellow color). I ran the test several more times on other tanks making sure the countdown was counting down. The other tank was 0 on API and the HANNA was 52.
ANYONE else have anything new to add over what has already posted ?
