Aquarium Pharmaceuticals Nitrate Test Kit for Freshwater/Saltwater Aquariums

Why Test For Nitrate? Nitrate (NO3-) is produced in the aquarium by biological filter. Beneficial bacteria in the biological filter convert toxic ammonia and nitrite into nitrate. A high nitrate level indicates a build-up of fish waste and organic compounds, resulting in poor water quality and contributing to the likelihood of fish disease. Excessive nitrate also provides a nitrogen source that can stimulate algal blooms. In the opinion of many aquarists, maintaining a low nitrate level improves the health of fish and invertebrates. Testing Tips: This test kit reads total nitrate (NO3-) level in parts per million (ppm) which are equivalent to milligrams per liter (mg/L) from 0 ppm to 160 ppm, in either fresh or saltwater aquariums. This test kit measures nitrate as nitrate ion or "total nitrate." Other nitrate test kits that measure "nitrate-nitrogen" (NO3-N) will give readings 4.4 times less than this test kit.Directions for Testing Nitrate: Read thoroughly before testing. Do not allow Test Solutions to get into aquarium. To remove childproof safety cap: With one hand, push red tab left with thumb while unscrewing cap with free hand.Fill a clean test tube with 5 ml of water to be tested (to the line on the tube). Add 10 drops from Nitrate Test Solution Bottle # 1, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops added to the water sample. Cap the test tube and invert tube several times to mix solution. Do not hold finger over the open end of the tube, as this may affect test results.Vigorously shake the Nitrate Test Solution Bottle # 2 for at least 30 seconds. This step is extremely important to insure accuracy of test results.Now add 10 drops from Nitrate Test Solution Bottle # 2, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops to the water sample. Cap the test tube shake vigorously for one minute. This step is extremely important to insure accuracy of test results. Wait five minutes for the color to develop. Read the test result by matching the color of the solution against those on the Nitrate Test Color Chart. The tube should be viewed against the white area beside the color chart. Color comparisons are best made in a well-lit area. The closest match indicates the ppm (mg/L) of nitrate in the water sample. Rinse the test tub with clean water after each use.What the Test Results Mean: In new freshwater and saltwater aquariums the nitrate level will gradually climb as the biological filter becomes established. A nitrate level of 40 ppm (mg/L) or less is recommended for freshwater aquariums. Many marine aquariums prefer to keep nitrate levels as low as possible, especially when keeping invertebrates.Monitoring Nitrate Levels: Regular testing for nitrate is an essential part of routine aquarium maintenance. Aquarium water should be tested for nitrate once a week to make sure the nitrate does not reach an undesirable level. Reducing Nitrate in the Aquarium: Partial water changes are easiest way to lower the nitrate in a soft water aquarium. Keep in mind, however, that the biological filter constantly produces nitrate. Also, because many tap water supplies contain nitrate, it can be difficult to lower nitrate levels by this method. Aquarium Pharmaceuticals Tap Water Purifier will remove all pollutants, including nitrate, from the tap water-making water changes effective. The Tap Water Purifier makes any tap water perfect aquarium water. Harmful Xn Corrosive C. Bottle# 1 contains 41% hydrochloric acid, causes burns, irritating respiratory system, harmful if swallowed, keep locked up and out of reach of children. In care of contact with eyes or skin, rinse immediately with plenty of water ( at least 15 minutes) and seek medical advice immediately. Remove contaminated clothing, wear suitable gloves and eye/face protection. In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
