Today we conducted a test on pH levels ,General hardness,Nitrite and nitrate. we had three groups that conducted the test. It was based in three different fish tanks with different conditions and environment.

Tank A environmental conditions
Snails
plant
Amazon plant
 Tank B environmental conditions
Dark
lot of algae
led lighting
Floating plant

Tank c environmental conditions


Florescent light bulb
mechanical filter
gravel substrate

 The results are not constant due to the environmental conditions that the fish is living in and the sizes of the fish tank. The lack of experience while recording data and in accurate reading
