This Aquaponics system has been set up at our school, Urrbrae Agricultural High School and sets an example for this project on Aquaponics. The system here involves Silver Perch Fish, with mint and other herbs. This system uses a pipe to pump the fish water into the container which contain the plants, and then gravity flows the water back into the Fish tank.
We tested Fish tanks with Plants and without plants, but we also tested our own Aquaponics system to compare the different levels of Nitrite, Nitrate and Ammonia. We noticed that
(These notes were taken on the 5/8/16).
Fish Tank With Plants:
Ammonia = 0.25 ppm (mg/L)
Nitrite = 0 ppm (mg/L)
Nitrate = 40 ppm (mg/L)
Fish Tank Without Plants:
Ammonia = 0 ppm (mg/L)
Nitrite = 0 ppm (mg/L)
Nitrate = 160 ppm (mg/L)
Our Own Aquaponics System:
Ammonia = 0 ppm (mg/L)
Nitrite = 0 ppm (mg/L)
Nitrate = 0 ppm (mg/L)
These results show that the plants really do absorb the nitrate. The water with plants have very low levels of nitrates, but the tank that doesnt have any plants in it has a high level of nitrates. The tank without any plants has 4 times the amount of nitrates than the tank that had a few plants in it and an extremely high amount compared to our own aquaponics system which has many plants.
