Sera Copper Test (Cu)

The sera Cu test is a water test for checking the copper content in the fresh and saltwater aquarium, as well as in the garden pond.

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.

Copper (Cu) is particularly toxic to invertebrates such as shrimps and crabs, but fish are also very sensitive to elevated copper levels. Cause of copper enrichment may be of versatile origin, for example, copper pipes, but also drugs or algae-destroying treatments.

Whether fish or invertebrates are safe, can quickly be detected with the sera Cu test.
