Sera

Both fish waste and feeding are possible causes for phosphate introduction into the water. A part is taken up as a nutrient by plants, an excess, however, provides nutrition for unwanted algae.

Nitrate (NO3) is an indicator for severe organic pollution. Sufficient for approx. 60 measurements.

Iron (Fe) is an important component of plant nutrition. In case the plants have fading leaves this may be due to lacking iron.

Makes it easy to monitor the ammonium/ammonia level in fresh and marine water

Permanent CO2 monitoring. CO2 is among the most important nutrients for aquatic plants. Deficiencies can therefore have severe consequences.

This test monitors the calcium level easily and precisely in steps of 20 mg/l (ppm). For approx. 7.500 mg (ppm) calcium.

The sera aqua-test set allows monitoring the parameters important for fresh and marine water – pH value, carbonate hardness (KH), total hardness (GH) and nitrite (NO2).

Die Aqua Test Box enthält ph, GH, KH, NH3/NH4, NO2, NO3, PO4, FE und je nach Ausführung CU oder CLTest in einem stabilen Testkoffer.

The sera O2-Test monitors the actual oxygen level in the water within minutes and allows for acting in time. Sufficient for approx. 60 measurements.
