Through waste produce (through dead food or fish waste) the nitrogen cycle is triggered and eventually leads to the presence of nitrates. Nitrate+nitrite N is of particular concern in estuarine or salt water systems as N is the primary nutrient that stimulates plant and algae growth there, often called the limiting nutrient. Nitrogen is often introduced into a pond system by fish some way or another. Before diving into the dangers, let’s get a better understanding of what nitrates are and how they develop in ponds. Nitrates have the same effect on aquatic plant growth as phosphates and thus the same negative effect on water quality.

Nitrosomonas bacteria in the filter convert the ammonia to nitrite and then nitrobacter bacteria convert the nitrite to nitrate. Based on the available evidence, EFSA’s experts concluded that existing safe levels for nitrites and nitrates added to meat and other foods are sufficiently protective for consumers.

Nitrite also has a rather sinister effect on the pond fishes blood, as it will bind very tightly with the red pigment and thereby preventing the blood cells from absorbing vital oxygen from the water. Game Changer – The Quattro-DB Ultrasound Algae Control System Is Here, Act Now: Proposed Regulation Could End Access To Koi. The best way to treat high pond nitrate levels is to use a complete solution that will remove nitrates entirely. In an effort to remove it through the process of oxidisation and create nitrites. Nitrate is not especially harmful to freshwater fish but is a potent plant fertilizer and can contribute to the growth of unsightly and unwelcome algae, such as green water or blanketweed. The straightforward signs can be observed in fish behaviour within a pond. We’ll it’s pretty simple and straightforward for the most part.
