Sera Phosphate Test (PO4)

The sera PO4 test is a water test for checking the phosphate content in the freshwater 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.

In natural, uncontaminated waters phosphate contents are rather low and in short supply. In the aquarium or garden pond, concentrations of 10.0 mg / l and more often occur. They are produced by strong fish stocking, phosphate-rich feed and phosphate-containing plant fertilizers. High phosphate levels in combination with high nitrate levels often lead to excessive algae growth. Part of it is taken up by the aquatic plants as food, but an excess quickly leads to unsightly algae. The sera PO4 test provides quick and reliable information about the current phosphate content.
