For diagnosing an actual problem, liquid is what you want.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy nitrate always reads zero. Is that right?\u003c\/strong\u003e\u003cbr\u003eUsually not. The nitrate test needs bottle 2 shaken hard for the full time the instructions state, and the capped tube inverted for the full time as well. Skipping that reads low.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo the reagents expire?\u003c\/strong\u003e\u003cbr\u003eYes. Each bottle carries a lot and date code.
