Measuring of abiotic factors in the Aqurium

1. temperature

We missed with the help of a thermometer the temperature at 3 different places in the cold water aquarium.

1 place: On top
18°C



2 places: Middle
18°C





3 places: Below
18°C



the temperatures in 3 passed away places in the aquarium were always same.


2. Light

We missed with a light measuring instrument the occurring light in different to places.

1. light under the HQI light:
26 246 luxes (There the measuring values were very fluctuating, has calculated we from 10 measuring values the average.)´



2. Light of the cover: 328 luxes




3. light of the window: 9,383 luxes




4. light of the ground: 140.7 luxes


3. have measured pH factor

as us the carbonate hardness of the aquarium water, we could read in the test rod the pH factor.
ph factor = 8.5






4. Oxygen salary

We missed with the help of an oxygen salary measuring instrument the oxygen salary of the aquarium water.
Oxygen salary = 8 mg / l
