Green water can last indefinitely.  I had a 55 gallon with green water and
a bunch of well-fed platties that stayed in the pea soup stage for 3 years.
Finally, I took the fish out and introduced Daphnia, which cleared the
tank in about two weeks.  I let the plants grow for around 4 months and
then reintroduced the fish.  The tank has stayed clear for four years to
the present.  I believe that the more dense growth of plants is the cause
for the green water not returning.
