Any idea where the nutrients are comming from? Finding the source and reducing/eliminating it is a good start. What do you feed, are the bulbs old, are you using sponge filters anywhere in the tank, is your skimmer not working.. ect ect ect...?

This green water syndrome or whatever is usually caused by really high Phosphates in the water. Maybe try a phosphate sponge?
