Use aquarium controllers, monitors and test kits to measure key water parameters.
All living organisms, even plants, require oxygen to survive and thrive.
A low oxygen concentration will cause the aquariums inhabitants to slowly suffocate making them increasingly likely to become ill.
Oxygen is also required by an aquariums biological filtration to convert toxic ammonia and nitrite to nitrate.
The Tetra Test enables you to easily measure oxygen levels in your aquarium to ensure that you are providing suitable conditions.
An easy guide and comparison chart is included.
Each test kits provides around 30 tests.
Tetra Test CO2 measures the carbon dioxide value reliably and precisely. Just like fish, plants also breathe by absorbing oxygen (O2) and emitting carbon dioxide (CO2). Under the influence of light, however, plants can carry out a process, which is known as photosynthesis. During photosynthesis, CO2 is absorbed (as food) and O2 is emitted. For this reason, plants require a constant supply of CO2 to ensure their strong and healthy growth. Good ventilation, e.g. using an air stone, ensures that your fish receive a plentiful supply of oxygen, but at the same time reduces the CO2 concentration, thus minimizing the most essential form of nutrition for your aquatic plants. By regularly controlling the CO2 values, you can ensure that sufficient carbon dioxide is available for healthy plant growth.
The following values are guidelines for CO2 concentrations in ventilated aquaria:
Tetra Test CO2
+ for all freshwater aquariums
+ for a large number of analyses
+ excellent long-term stability
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.

Tetra Nitrate Test Kits will help you to monitor the health of your freshwater or marine aquarium.
Nitrate is the end product of biological filtration and the result of decomposition of nitrite. It can also be present in tap water supplies. It is a key cause of algae growth and in high concentrations can cause fish and plant health problems as they are starved of nutrients.
Use the Nitrate Test Kit every 1-2 weeks to monitor levels properly and use Tetra Nitrate Minus to remedy the problem. In a new aquarium you may need to test every few days to make sure that the filtration system is working properly.
This kit uses a colour change system to give accurate results, simply compare your findings to the colour chart included.
