1x Nitrate Test from Terta The nitrate test enables you to reliably determine the level of pollution in your aquarium water. The measured nitrate value shows when and how much water needs to be changed. Organic nitrogen-containing substances such as fish droppings, leftover food and dead plant parts are broken down by special microorganisms in various stages. From ammonia/ammonium, to nitrite to nitrate. Nitrate is a nutrient for plants, but in concentrations above 50 mg/l it is increasingly harmful to your fish and promotes unsightly algae growth. To maintain optimal water quality, the water values should be checked weekly.
