Nitrate Water Test Kit

High pond nitrate levels are not only problematic for fish. If nitrates are not removed from the pond, they can also cause the build-up of algae. Leading to other pond problems such as blanket weed and green water. Nitrate (NO₃) – nitrite is converted to nitrate (NO₃) by nitrifying bacteria. While nitrate is far less toxic to fish and other aquatic organisms than ammonia and nitrite, it can stunt your fish’s growth and long-term exposure to high levels stresses them and compromises their immune systems. Nitrate is also a major contributor to algae growth. Some tap water sources are high in nitrate, so it is a good idea to test your tap water before using it. Nitrate toxicity to fish varies depending on species, age and overall health, but levels above 50 ppm are undesirable in freshwater aquaria. Regular partial water changes, proper filtration, sensible stocking and feeding habits as well as the use of live plants will help keep nitrates in check.
