For approx. 420°dGH.

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.

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.

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.
