    Never spray the screen with a hose or sink sprayer, that removes the algae from the holes of the screen. You want that algae to stay in place as much as possible. On a UAS I have found the holes do not fill in at all though. So you have to rely on what has 'grown on' to the screen material itself for re-growth.

    The growth you describe sounds like dinoflagellates. It is what I used to get when I was starting up the screen, and is what I get if I run my LEDs without a diffuser and/or for too many hours/day.

    But my answer is yes, clean the screen, but just remove it carefully and rinse the dinos away by gently running your fingers over the screen under slow running room temp tap water. Just don't scrape or spray the screen.

    Scrape it clean when it is dark or black.

    It will not be worse, because it is blocking light anyway, and not growing any more, and is probably just letting go.

    Waterchange will not help much. Just let the screen grow.
