The Tetra Test Nitrite kit is a liquid kit which works by changing the colour of a water sample in relation to the nitrite concentration. Compare the colour of the sample to the easy-to-read colour chart (supplied) to determine the nitrite level of the water in ppm (mg/litre). Full instructions for use supplied in box.
Nitrite is produced from the biological breakdown of ammonia in the filter. Nitrite is highly toxic to fish but is usually removed from the water by the bacteria which live inside the filter. However, in new tanks or if the filter bacteria are damaged, the nitrite level may become toxic. The only way to know what the nitrite level is is by testing for it with a TetraTest Nitrite kit. Regular testing especially in new aquariums will prevent damage caused by nitrite poisoning
Instructions: To test the nitrite level simply take a sample of aquarium water in a jug and then use some of this to wash out the test vial. Then
fill the vial to the 5ml mark
hold nitrite reagent bottle number 1 upside down and add 7 drops close vial and shake gently
After 10 seconds add 7 drops of nitrite reagent number 2 close vial and shake gently
Leave vial to stand for 2 to 5 minutes for full colour development.
Ammonium and ammonia mainly arise from fish waste. They are converted into each other depending on the pH value. While ammonium is mostly harmless, ammonia is toxic to fish.
The sera NH4/NH3-Test allows monitoring the total concentration of both (the actual ammonia level can be calculated according to the pH value the using the included chart).
In case of acute danger, sera toxivec (freshwater) or sera pond toxivec (pond) provide help. sera bio nitrivec (freshwater), sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) actively counteract lasting enrichment of these substances.

Tetra Test NH3/NH4 to the reliable and exact determination of the Ammonia content in fresh and sea water aquaria. Organic nitrogenous substances in the aquarium, such as fish excreta and food remains, are decomposed in stages: first into toxic ammonia, then into nitrite and finally into nitrate (nitrogen cycle). An overall ammonia content (NH3/NH4+) of over 0.25 mg/l will cause long-term damage to your fish. It is also an indicator of abnormal nitrogen degradation or poor biological filtration. Packing contents are enough for 25 tests.
Makes it easy to monitor the carbonate hardness in fresh and marine water. For approx. 390dKH. In case of too low KH values we recommend sera KH/pH-plus (in fresh and marine water) or sera pond bio balance (in ponds) in case of too high values we recommend filtering through sera super peat (in freshwater aquariums).
Nitrate (NO3) is an indicator for severe organic pollution. The source of this organic pollution should be eliminated a partial water change provides immediate help. In the long run filtering through sera siporax Professional helps avoiding nitrate enrichment. Sufficient for approx. 60 measurements.
Nitrite (NO2) is among the most toxic substances for fish in aquariums. It can enrich in the water in case of insufficient biological filtration. The sera NO2-Test allows monitoring the nitrite level in fresh and marine water easily and reliably. We recommend using sera bio nitrivec (freshwater) sera marin bio reefclear (marine water) or sera pond bio nitrivec (pond) in case of slightly elevated nitrite levels. In case of severe nitrite problems sera toxivec (freshwater) or sera pond toxivec (pond) quickly provide help. Sufficient for approx. 75 measurements.
Both fish waste and feeding are possible causes for phosphate introduction into the water. A part is taken up as a nutrient by plants an excess however provides nutrition for unwanted algae. The sera PO4-Test quickly and easily provides an overview of current phosphate levels. Excess phosphate is easy to remove with sera phosvec (freshwater) or sera phosvec Granulat (fresh and marine water) or sera pond phosvec (pond). Sufficient for approx. 60 measurements.
Water test to quickly and easily check aquarium water quality in 60 seconds: test strips measure pH, carbonate hardness (KH), general hardness (GH), nitrite (NO2-), nitrate (NO3-) and chlorine (Cl2)
