Today we investigated three fish tanks which are hugely similar but different in a few ways. These are some differences and ways to research fish tank environments:
Tank A: We looked at this tank last and noticed that compared to the other two it was the greatest, it had the largest plants as well as the largest fish. The tank was mechanically filtered in a cycled motion, and there were traces of algae residing on the surface of the tank as well as dirt(maybe ammonia) on the surface of the rocks(which were tiny pebbles) and on the glass. A fairly long fluorescent light burned on top of the tank as I presume that the fish in the tank are fond of various light sources.
The water was not extremely clear (fairly yellowish) I would say.
The temperature was bordering on 27-28˚c
The ph level was slightly acidic at 6.8
There were no traces of nitrite
Nitrate ranged at 250
KH levels at 6
And GH of the water at 16
Tank B: This tank was quite murky, brownish in colour, as it had a box filter being operated and presence of algae on the rocks. The fish were small and the tank was not placed in very light area.
The temperature was 25˚c
Ph: 6.4
Nitrite: 1
Nitrate: 100
KH: 0
GH: 10
Tank C: Water was quite clear and much activity seemed to be taking place as there many plants, snails etc. This tank had a cycled filter which works extremely well with that kind of environment.
Temperature: 29˚c
pH: 7.2
Nitrite: 0
Nitrate: 25
KH: 6
GH: 10

Therefore in conclusion, the cleanest fish tanks would be tank tank A and C as the pH levels are closest to neutral baring in mind that the levels of the constituents are not constant at any given time.
