    do it straight out the gate too. makes a huge difference on cycle time. at least mine usually do. that and your not trying to throw a screen into a high nutrient ( oh s@#t) situation so you can skip the gooey black stuff. I didnt even get diatoms this time around.

    still have cyano though (scratches head)

    Whats your opinion on using violet 405-415nm instead of blue 455nm leds?

    I'll be testing the 660/455 against 660/422.5 (Steve's LEDs "True Violet") at some point in the near future to see if this does indeed make a difference. But the general thought is that 455nm LEDs cover enough of both the A and B spectrum - there is really only a supplemental need for blue, as red is the highly dominant need.

    I've just finished my scrubber last week and I'm using violet and red LEDs. It's only been running a week and has started to grow algae but I'm thinking now I should have gone with 455 blue insted, mabye.

    This is a view of mine, two red 625-630nm on the outside and one violet 405-415nm in the middle. In the flesh the eye sees the middle Led as very dull almost as if its not working properly but when I took this picture with a camera (iphone) it shows the violet is just as bright as the outer red Leds.

    I am using a combination of red 660 nm LED's with some blue 455 in the middle. Getting really high growth where the blue LED's are vs. just the red.

    long hairy algae where the blue/red combo light is.

    Looks like the combination is better than red alone.

    Yes Ace or Kerry did the same test and got the same result. The observation he made was that the blue enhanced the growth, as in it made it bulkier or 'sturdier' - harder to scrape. But most people that have compared the two (with and without blue) have noticed the same effect.
