> From: tconnors at webtv_net (Thomas Connors) > Can anyone recommend a low range, EASY to read NO3 test kit? If the emphasis is on EASY, it is hard to beat the Hach Nitrite/Nitrate test strips. Dip in water, 1 minute later read color. Range steps are at 0,1,2,5,10,20,50 ppm. Hach catalog # 27454-25 Jon Wilson
