    Hi Tom welcome back. We are good.

    You probably can do 18 to 20 hours of light. Also it looks like the bubbles are more on the left side of the picture, and not enough on the right side. Maybe you can adjust them.

    Clean it all out with a toothbrush and see how it looks in 10 days.

    Good morning SM.

    Thanks for reply.
    I made the changes you sugested -18hour / day of light. Let us see how it will be in 10 days.

    About the bubbles, i think it is igual all over the screen. I think that the difference we see in the pic is becouse the last time i cleaned only the right side of the screen. Can it be the reasson?

    Thanks a lot.

    Welcome back. Looks like it is growing well, and pulling lots of nutrients out of the water.

    You need more light, and longer hours of light.

    Brush out good, more often, to remove the dark growth.

    Corals: trumpet. Carpet green and brow, kenya , green star polips. And others
    I have a lot of brown algae all over my rocks, and i need to clean my glass every 3 days.

    Sounds like too much light, for a new screen. Cover half the lights with a black cloth, and check growth in 1 week.

    Good morning SM.
    Yes i think its growing a little bit longer, and very separated each portion of algae.
    Do you think it's good to let it grown for more than 7 days?
    12 x 660nm leds is enough?
    Thanks again
