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.\u003c\/p\u003e\u003cp\u003eAmmonia 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.\u003c\/p\u003e\u003cp\u003eIn this test, the total concentration of ammonium \/ ammonia is measured. In freshwater applications, a total concentration of ammonium \/ ammonia of 0.1 mg\/l (ppm) is normal under standard conditions, although an upper limit of 0.5 mg\/l (ppm) should not be exceeded. 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. After a measurement has been taken, the ammonia concentration in the water can be determined.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePackage Contents\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e20 ml \/ 0.68 fl.oz. of reagent A\u003c\/li\u003e\n\u003cli\u003e10 ml \/ 0.34 fl.oz. of reagent B\u003c\/li\u003e\n\u003cli\u003e10 ml \/ 0.34 fl.oz. of reagent C\u003c\/li\u003e\n\u003cli\u003e1 glass cuvette 10 ml\u003c\/li\u003e\n\u003cli\u003e1 dosing syringe 5 ml\u003c\/li\u003e\n\u003cli\u003e1 measuring spoon\u003c\/li\u003e\n\u003cli\u003e2 colour cards\u003c\/li\u003e\n\u003cli\u003eInstructions for use\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eInstructions For Use\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDetermining the total concentration of ammonium\/ammonia:\u003c\/p\u003e\u003col\u003e\n\u003cli\u003eShake the dropper bottles before use!\u003c\/li\u003e\n\u003cli\u003eRinse out the glass cuvette with tap water and then several times with aquarium water.\u003c\/li\u003e\n\u003cli\u003eFill the glass cuvette with exactly 5 ml of aquarium water using the dosing syringe.\u003c\/li\u003e\n\u003cli\u003eNow add 10 drops of test reagent A to the water sample, close the glass cuvette using the stopper and briefly shake the solution.\u003c\/li\u003e\n\u003cli\u003eThen add 5 drops of test reagent B to the water sample, shake the glass cuvette briefly again and set it aside.\u003c\/li\u003e\n\u003cli\u003eThen add 5 drops of test reagent C to the sample, shake the glass cuvette briefly again and set it aside.\u003c\/li\u003e\n\u003cli\u003eAfter 6 minutes of development time, place the glass cuvette on the white inner circles of the colour card and compare it to thes urrounding colour field.
