Sera pH test

The sera pH test is a water test to check the pH in the fresh and saltwater aquarium, as well as 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 his 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.

In order to stabilize the pH value, the carbonate hardness should always be at least 5 ° dKH, otherwise, there is a risk of acid levels falling! Please always measure the carbonate hardness (with the sera kH-test) and increase the carbonate hardness to at least 5 ° dKH (in the aquarium with sera KH / pH-plus), and also check just before you change the pH-value.
