Finally! 90g scrubber - 40sq inches

I would clean it, at least get all the black growth off.

Thanks Floyd, I will give it a rinse tonight, that darker slimy crap comes off really easy anyway.

More nutrients is the same as needing more light.

I am not sure exactly what you mean by that. Do you mean that with more light the nutrients will get "soaked up" more quickly because it will get me green growth?....or do you mean that we can't tell if it is low light or too high of nutrients based on color alone?

Is it suggested i ramp up the lighting until the nutrients come down, or do I just go with the flow, clean more often until the algae lightens up in color?

My take on Santa Monica's statement is: More Light = More energy for photosynthesis to happen, which means more nutrients will be taken in during photosynthesis.

Yes.

Thanks. I have the standard light socket with clamp to the side of my sump(29g standard tank). The 42w CFL are very large and expensive($10 each up here), does anyone have experience to know if the clamps are strong enough to hold with the extra weight?

Well I went ahead with the cleaning a couple days early because of the slimy growth. I am going to give it another week with the lights that I have right now. Great news, underneath the slime there is green galore. Here is the pic of the cleaned screen, hopefully this is a catalyst to more long stringy green algae.

tested nitrates and I am closer to 20 now, hopefully some day i will have a yellow test instead or orange or red!

algae definitely starting to lean towards brown again, but I am patient.
