    Clean as soon as you start getting those dark areas. And clean everything off the screen.

    Those horizontal screens take a LOT longer to grow in. I have also noticed and only clean mine (now that the screen is mature) every three weeks. Here is a pic of my horizontal 3D growth. This took over a month to get just OK growth. If I had a better reflector this may not have taken as long. Good luck.

    sorry if i wasnt specific....

    It is a vertical screen....not.horizontal.

    The dark growth in the picture is actually in person looks like light green how do i clean it....last time i cleaned there was sheets of algae coming of and i had to clean it completely off...it left nothing to seed.

    And during this extra time of darker growth, the roots die. That's why horizontal is not as effective.

    I wondered about that, it was hard to tell by the pic, the single sided are still a little slow going like the horizontal due to the single side of light. I use the card in the pic above to clean mine. Some times I take plastic bristle brush to it.

    Very true, the nutrient reading on the horizontal tank are never as good as the vert double for sure. I have noticed that if I go 3 weeks on the horizontal I get little better nutrient readings but its not much. With two week cleaning on the horizontal I get about 5-10ppm nitrate with three week cleaning its closer to 5ppm. I have not done a scientific report and charted the numbers it was just something I noticed since I have been doing 3 week cleanings for the last 2-3 months.
