Aquarium Pharmaceuticals Nitrite Test Kit

Koi and goldfish excrete ammonia from their gills. Urine and solid fish waste breakdown into ammonia. Decaying plants and algae also release ammonia into the pond. Uneaten fish food will also decompose and release ammonia into the pond. Ammonia is converted to nitrite by nitrifying bacteria in (biological filtration). Nitrite is very toxic to fish. Nitrite is absorbed by the fish Once in the bloodstream nitrite binds to hemoglobin and prevents the blood from carrying oxygen. This prevents normal gas exchange across the gills. Fish will become weak and susceptible to a variety of diseases. Eventually fish will die from oxygen starvation. It is impossible to see or smell nitrite in pond water. The only way to know if ammonia is present in the pond is with a nitrite test kit. Use the Pond Care Liquid Nitrite Test Kit to accurately measure the nitrite level in ponds and water gardens. Directions for Use: Read thoroughly before testing. Do not allow test solutions to get into the pond. 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 5 drops of Nitrite Test Solution, 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 shake the tube for 5 seconds. Do not hold finger over the open end of the tube, as this may affect test results. Wait five minutes for the color to develop. Read the test results by matching the color of the solution against those on the Nitrite 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 nitrite in the water sample. Rinse the test tube with clean water after each use.
