Nitrate (NO3) is the end product of the degradation of ammonia by nitrifying bacteria in your aquarium or pond. Nitrate is not toxic for fish and thus is no direct problem for the health of fish like ammonia or nitrite are; high concentrations however can in the long run reduce growth and reproduction of fish. Indirectly, nitrate can lead to algae problems as nitrate is one of the key nutrients for algae and plants. Plants and algae compete with one another for nutrients and unfortunately plants can't always win this competition. In such a case algae can grow and even explode in numbers. In a pond this results in either turbid, green water or in mass amounts of thread algae. In aquaria algae can completely cover the glass, stones and even plants, leading to their death. Although nitrate is basically not toxic, it is highly desirable to keep the level low to prevent algae growth. For fresh water we advise a threshold of 50 mg/l. This can best be accomplished by making regular water changes.
