The class was spilt into four groups and we were told to test the water chemistry of the three different aquariums in the room. All four of the groups tested the water, however, group three's results was inaccurate so I will only be referring to the results from Group 1, Group 2 and my group, Group 4.
My groups observations and findings:
Tank A:
- Large wood piece
- plus minus 10 rocks
- under gravel filter
- A lot of larger fish compared to the other two tanks
- Quite a few plants
- gravel/pebble substrate
- Heater (27'C)
- pH level of 6,8
Tank B:
- Tinted water (black water set-up)
- floating plants
- Box filter
- Algae build up on rocks
- few snails (2 or 3)
- small wood piece
- Heater (25'C)
- Oxygen stone (air supply)
- pH level of 6,4
Tank C:
- Heavily planted tank
- Clear water
- Lots of snails
- Small wood piece
- Water movement
- Built-in under gravel filter (I think)
- Sand substrate
- pH level of 7,2

Group 4 Results:
Tank A- the largest and the tank that looks like it would be the most maintained, turned out to be the worst tank, because of its high level of Nitrates.
Tank C- This was proved to be the best tank out of the three due to its low level of Nitrates and its good pH value.
