Nitrite (NO2–\u003cspan\u003e), which is highly toxic to freshwater species in particular, is produced in the first stage of the bacterial process. If the nitrification process works, nitrite is converted to the comparatively non-toxic nitrate in the second stage.

An algal bloom is often the result of a high nitrate level in an aquarium. Some reef aquariums have ultra-low nutrient conditions – nitrate shortages can occur in cases such as these. Therefore, the nitrate concentration in the aquarium water should be tested regularly. It is advisable to keep the nitrate concentration in freshwater aquariums below 50 mg\/l (ppm), whereas the concentration should not exceed 20 mg\/l (ppm) in saltwater applications. When nurturing hard coral, the aim is to keep the nitrate concentration below 10 mg\/l (ppm). \u003cspan\u003eLower limits for nitrate depend on the general conditions in the aquarium.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003eWith the high resolution Tropic Marin® Nitrite\/Nitrate-Test Professional\u003cspan\u003e the nitrite and nitrate concentrations can be determined with a particularly high accuracy in the low concentration range between 0 and 1 ppm for nitrite and between 0 – 20 ppm for nitrate.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cdiv\u003eBenefits:\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cspan\u003e\u003cspan\u003e• \u003cspan\u003eMeasurement range: NO2 0 – 1,0 mg\/l (ppm)\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e• \u003cspan\u003eMeasurement range: NO3 0 – 20 mg\/l (ppm)\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e• Accuracy: NO2 0.002 mg\/l\u003cspan\u003e•\u003cspan\u003eAccuracy: NO3 0.05 mg\/l\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e• For determining the nitrite\/nitrate concentration in aquaria\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e• Incl. comparator and phosphate standard to check function and shelf life of the test reagents\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e• \u003cspan\u003eSufficient for approximately 50 applications\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cdiv\u003eHow to use:\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\u003cspan\u003eDetermining the nitrite level:\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003e1.Shake the bottles before use!\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e2.Rinse out the glass cuvette with tap water and then several times with aquarium water.\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e3.Fill the glass cuvette with exactly 15 ml of aquarium water using the dosing syringe and place it in the comparator which serves as a cuvette stand.\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e4.\u003cspan\u003ePlace the dropper tip on the 1 ml dosing syringe, add 1 ml test reagent A, close the glass cuvette using the stopper, briefly shake the solution and place it back in the comparator.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan\u003e\u003cspan\u003e5.Then add 4 drops of test reagent C, close the glass cuvette once again, shake it briefly and place it back in the comparator.\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e6.\u003cspan\u003eAfter 3 minutes of development time, place the glass cuvette in the comparator on the white circles of the nitrite colour card in such a way that the second free opening on the comparator (without cuvette) is underneath the colour card (not on the colour fields) and the narrow end face of the comparator is facing the colour fields.

Depending on the pH value, there is an equilibrium between ammonium ions NH4+ and ammonia NH3 in the water. If the pH value is less than 7, the largely harmless ammonium ions are dominant, while the presence of ammonia grows if the pH value is above 7. Ammonia is very dangerous as it impairs the breathing capability of living beings. It penetrates the cells easily, causing the pH value to rise and inhibiting vital functions. In a healthy and well-established tank, ammonium ions are quickly oxidised by nitrifying bacteria into nitrite and, in turn, into nitrate. If this chain of events is disrupted, the concentration of ammonium can suddenly rise. Therefore, the concentration of ammonium\/ammonia should be tested, especially in new tanks.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eIn this test, the total concentration of ammonium \/ ammonia is measured.

In saltwater, the total concentration of ammonium \/ ammonia should be smaller than 0.05 mg\/l (ppm). However, the crucial point in this respect is the pure concentration of ammonia, which is dependent on the overall situation defined by the temperature, the pH value and the total concentration of ammonium \/ ammonia in the aquarium.
