    Placement looks good, should give you pretty even coverage.

    when i made my light i place in 5 led light Wave Length (nm) : 472 , 3 pointing down and 2 pointing little back.
    when the pics taken i have the power at 9 volt little to bright i think, so now i have switched down to 6 volt.
    hope someone understand my english .:worried:

    edited the volt after i look under the tank i not started at 12volt

    Nice! I might be getting a transformer that can switch voltages. Also, how many ohms of resistor are you using for each LED? If I remember the math right, from my electronic courses...I can use 150ohms for each LED with no problem for up to 8 LEDs, right?

    Thanks!
