I had a 55 gallon once that had green water for at least 2 years, as I
recall.  It had a lot of big fat overfed platies in it, and it only cleared
up when I removed all the fish and put in some Daphnia.  After it cleared
up, the plants grew a lot thicker, and I was able to return the fish
without the green water returning.
