or the nutrient levels in the water are too high?

Same thing. High nutrients need more light to get green. Without more light, high nutrients give brown, which hopefully removes enough nutrients to get to green evenually. But no matter what the nutrient level, very strong lighting can get green in the first week (recent discovery). Then, the lighting can be reduced later, if desired.
So I add another 2x22w CFL bulbs like in the picture?
Would help. Move them to the sides so they cover the screen more evenly.
imagine the bucket beeing square (Lights mounted in the lid, hanging down into the bucket.)
Previously it was like this:

Now it's like this:

[/code]
Much better.
This is quite peculiar, but i have green hair algae on the drainpipe opening out of my bucket (2-4cm away from the bottom of the light). They are growing rapidly and healthy fully submerged. On the screen there is still no visible growth of GHA and the flow should be decent after I upgraded to a 1700 lph pump with only 1m to lift the water. I added a second layer to not get the slot to work as a sprinkler system.
It does seem like I'm getting alot thicker growth, but nothing looking like the really green stuff (except on the screen INSIDE the flow pipe and on the drainpipe wich is neither roughed or lighted atm).
Let it run for another couple cleanings.
i should run it 18-6, cleaning every 7 days?
It's yellowgreenish atm, thick at some spots, looks like short hair.
Yes
