    You have nothing to clean off, so no, don't clean it. Something is not right if you still have a bare screen after this long. Do not clean at all until you have some growth. Let it grow for another 14 days then post another video or pic.

    Also, you need to siphon all of that cyano out of the tank at least a few times a week. Never let it get that thick, that is competing with your algae scrubber. Remove it all as often as needed!

    Yes I think you need to siphon all the cyano out. Don't clean the scrubber.

    ok iīll do that,
    but whats is wrong in my algea scrubber?
    tank + sump: 71 gallon
    screen: 7,5" x 7,5"
    light: 1x 25w and 1x 18w each side - total=86w
    flow: i cant measure this, but i think is good, but i can change it if necessary to more or less flow,
    try to see by the video if my flow is good.

    the screen is new it has 7 days now.
    my last one was so patched because i did many changes in it to fix some problems.
    so, i wanna ask you all if this kind of growth is normal for a seven days screen?
    I thank you Bacon and SM for help me.

    Have a nice night

    Light level is good. Reflectors look good too. This is not the issue.

    try to see by the video if my flow is good.
    Flow looks fine to me. This is not the issue

    but whats is wrong in my algea scrubber?
    There's nothing wrong at this point because...

    the screen is new it has 7 days now.
    ^^ this. you can't expect a brand new screen to grow algae instantly. It takes several weeks, sometimes several months for algae to attach and grow. IN the meantime, you need to remove anything that is competing with it. Don't just let the cyano take over. The cyano is likely competing with your scrubber at a chemical level. Meaning, the cyano is releasing chemicals into the water to inhibit the growth of other algae, including the algae on your screen. You need to get rid of that cyano!

    I would also run som activated carbon to remove the cyano-produced chemicals from the water. This will not hurt your scrubber, in fact, it may help to put the carbon in line before your scrubber to remove any of these chemicals before the water gets to the scrubber screen.

    so, i wanna ask you all if this kind of growth is normal for a seven days screen?
    Yes, normal for 7 days. Don't clean it unless you have:

    1) growth that covers the whole screen
    2) a slime coating (yellow or brown/black) that is preventing growth from attaching

    In either case, when you clean the screen, you only need to swipe your palm across the screen and then lightly rinse

    Just a helpful hint, you can embed the videos by clicking this little icon

    I think he meant that it is 7 days from last cleaning.

    I do think the cyano is the problem. Is the most cyano I have ever seen.
