This kit reads it from 0 to 160 ppm in fresh and salt water, roughly 90 tests per kit. Sustained high nitrate rarely kills outright; it shows up as fish going off their food and looking flat, and as algae that keeps coming back.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is in the kit\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2 test solutions\u003c\/li\u003e\n\u003cli\u003e1 test tube with cap\u003c\/li\u003e\n\u003cli\u003eColour chart and instruction manual\u003c\/li\u003e\n\u003cli\u003eAround 90 tests\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eReading it properly\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSolution 2 has to be shaken hard for the full time the booklet states, and the capped tube then inverted rather than shaken.
