Description

The sera O2 test is a water test for checking the oxygen content in the freshwater aquarium and in garden ponds.

Determine water values
pH value, carbonate hardness (KH), ammonium and nitrite are among the most important water parameters. Extreme deviations from the target values can suddenly become an acute danger to life. Whenever the appearance or behaviour of the fish is conspicuous, or other peculiarities (eg sudden dying of aquatic plants) in the aquarium are noticeable, the basic water values should be checked first. For routine control, the easy-to-use test strips can be used. For more accurate results, we recommend the test of the sera aqua-test box in a sturdy plastic case. Total hardness, nitrate, nitrite, phosphate, iron, copper, chlorine, silicate and oxygen should be known to the experienced aquarist as averages in their aquarium. Checking these values every now and then is usually enough. If suspected (eg poisoning, algae problems, shortness of breath) these parameters should be examined more closely.

Fast breathing on the water surface is a sure sign of lack of oxygen and often intervention is already too late. The sera O2 test detects the actual oxygen content in the water in minutes and allows for rapid action. A quick increase of oxygen can be achieved with sera O2plus.

With the sera O2 test, you can check your oxygen content exactly and very precisely by means of a drop test!
