A high nitrate level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and algae growth. Maintaining a low nitrate level improves the health of fish and invertebrates, so aquarium water should be tested for nitrate to make sure it does not reach an undesirable level. Kit contains 2 bottles of liquid test reagent, 2 laminated, computer-calibrated color cards, glass test tube with snap-tight cap, step by step instructions and information on how to correct unsafe conditions.
