And then...
Three weeks later... in our aquatic ecosystem without
light, we can see a homogeneous dark gray colour in all of the column except
the top, where the colour is brownish with a fine red line
There aren't any important changes if we compare it to
two weeks ago, (look at the pictures). We can see the same homogeneous dark grey
colour in all the column. It happens because there are cellulose ferments
and sulfate-reduncing. At the top there are still bacterias living
between the part with oxygen and the part without oxygen. Water turbidity was
explained before...
See you son!!
