    I've seen seen several others who have used a diffuser and seemed to show improvement. My week old LED build was built with a diffuser from the get go. I think that if you have an imbalance of distribution of colors, like blue only in the middle, you would benefit to at least have the blue diffused. But For me it was easier to diffuse the whole array.
    Thread with my current build of UAS: Here
    150g seahorse system:
    75g seahorse DT
    25g deep sand bed fuge and cheato tumbler
    55g sump
    40g fuge for pod production

    Arduino based controller for dimmable LEDS and lights over fuges, heater/chiller, ATO and RO/DI production.
    Temps run between 70-73*F.

    I am of the opinion that diffusing when you group the LEDs closer than 2" spacing is required. On my UAS I put a 1" x 1" diffuser right in front of the blue LED, which was 1" from each of the reds and my screen filled in quickly. I diffused the whole array and it reach the growth level of the previous week in 4-5 days.

    All red works just fine too. I get hardier and longer growth with the blue added.

    That's probably a good idea.

    Any good updates for a UAS on a large tanks... say 600gallons? OR still think the waterfall would be better for it?

    Neither is better or worse. It's what you can build.
