    They are mounted to AMD processor chip heat sinks. I have the 4 reds in a square pattern and the blue in the middle. Sorry no pic. My screen is about 6x9.

    Here is this weeks pics before cleaning. This waterfall scrubber has 4 660nm on one side and 4 660nm and 1 450nm for a total of 5 on the other. Its pretty obvious what side has the blue 450nm. The growth speaks for itself. I have went many months waiting to see if it was just a fluke that one side did better then the other but it was like this every time. I even put the 5 count side further from the light and diffused it with two diffusers to make the light intensity more equal to the 4 count side. Still, the side with one blue blows away the all red side.

    Here is a pic from the side showing the 3D thickness.


    Here is the blue/red side.


    Here is the all red side.


    A close up of the red blue side.


    The algae grows right out toward the red/blue side, its crazy how is does this. This is almost 3 weeks worth and my screen is one cube over sized for what I feed.

    I am also gonna "blue up" my cfl's. Everything I read on the subject points to healthier growth with both ends of the photosynthetic spectrum covered.

    I hope to add a blue to the other side soon.

    Garf-I'd like to know how you are going to "blue up" your cfl's. That sounds interesting

    Gonna put a small 420nm actinic on one side to supply a level of blue, violet and uv. Although a 460nm actinic would supply blue to violet without the uv, I am curious as to the impact more UVa has on algae growth. Only gonna do it on one side though in case I have negative results and fry my screen.

    Thanks. I look forward to seeing the results. I found a bulb that includes both: AquaticLife 420/460nm T5 HO Fluorescent Lamp. This might be an option if yours proves to be successful with the 420nm actinic.
