Water can be a mysterious element of an aquarium.  Coarse contamination or clouding in the aquarium are obvious indications of a drop in water quality, but what about O2 content, degree of hardness and pH values? To ensure that the living environment is perfect for all the plants and animals, you need an aquarium water tester.

There is a fragile biological balance in an artificial underwater environment. Plants, animals and technology influence the condition of the water. While in an open body of water, fluctuations stabilise naturally, you, as an aquarist, must keep a constant eye on all parameters of the tank. Many fish and plants react very sensitively to disturbances in water values – the worst case scenario is the biosystem can tip over irreversibly. With a water test you can quickly detect critical nitrite values.

Commercially, there are water tests that can be used to determine a specific water value and others that record several values at the same time. Common readings for multiple test strips are:
