    I have two of theese led units, maybe i should try to solder the two of thees led configurations in parallell to one single driver.That would be half the effeckt on both led configurations, dont know if the driver can handle it but maybe it is worth a try. What do you think, maybe this will not solve my problem compleatly, but maybe it wil help some?

    I think the problem is too intense lighting on a virgin screen. The light is preventing proper growth from taking hold on the screen. Burning the life out of it. The energy is just too much. Lower lighting will give algae, although weak, a chance to get a foothold. This must then be ramped up to get any filtering capability. Can't you go back to cfl until your screen takes off ? Or use a pre cured screen from a waterfall.

    I would think that you would get a lot of spill light into the tank with the LEDs placed where they are. Not much you can do about that, unless you extend a shield between the fixture and the side of the tank. But that would look pretty weird having a box extend 7-8" off the side of the tank to the light fixture.

    I would think that if you placed a diffuser on the side of the tank and put the LEDs about 2" or 3" from it, that would work. You would still have the light spill problem, but a box extending only 3-4 inches from the tank to the fixture would look a little nicer.
