BRI1 Isolation Week 1

The first time we observed our allocated fish and we did not have any clue what to do to gather information for the update. After some time we have managed to see that the water control and the plant were important for the fish. Nitrates level were kept constantly at 25 mg/l to neutralize the decays and algae in the water, and so is the Nitrites which is toxic to the fish so the level was kept ast zero all the time. The pH level of the water was 6.4 or less

NO3 (mg/l)
NO2 (mg/l)
GH < 3
KH 3
pH < 6.4
