    I stopped dosing vodka cos my corals were bleaching and its not necessary with softies. Added Rowaphos but even before i stopped the vodka this started.

    Its so bad that my substrate clumps up so much i can actually peel it off see attached pics.

    Whats going on?
    oh yes its only where there is light wherever there is shade and no light its fine substrate is nice and clean and white


    Nitrate and Phos is zero.
    I intend adding a refugium in the coming weeks and have been doing regular 10% waterchanges. cut down feedings as well

    Have you doubles checked those readings, I find it hard to believe that the readings are zero and you have that problem.

    What is you Alk and pH?

    Those look like diatoms on your substrate. I agree with @lIghty about your nitrate and phos readings. Something in your tank is fueling the algae growth. You said you reduced the feeding, maybe you need to reduce your photoperiod for a while too.
    When are you going to add your refugium? At least then your macroalgae in the refugium will compete for the excess nutrients in your system and then ultimately reduce your nuisance algae

    Ziyaad , it looks like brown hair algea. The reason for your readings being zero is that all nutrients are now being consumed by the algea.

    Ziyaad , I would hazard a thought that because of stopping carbon dosing you basically "crashed" your bacteria population allowing the diatoms to become dominant and algea to grow under hightened nutrient levels.

    If it was me I would look at adding a bacteria source , increase water quality by more frequent WC and keep the rest as you are doing.

    The rowaphos will start doing it's job as well

    Whats your tds readings on the ro unit? I would also think you have too weak flow and lots of dead spots inside your tank.

    Eish, IMHO, you can't just stop vodka, agree with Suhaly, when you last change your filters on RO unit.
    Hope it comes right bud, I hate diatoms, ok mabe dislike them, they have a place on our eath!

    I agree increase Alk and magnesium. Lots of carbon and aeration of water.

    I have/had the same problem, could it not be sun light, Why i say that is because the change of season the sun is at a different angle shining through a window, my tank is close to a window and i have had this problem for a bout a month or so. SO i blanked of the window so no sunlight can come through and that crap is almost gone. Maybe i got a different problem but it is some thing worth looking into

    Looks like a mixture of cyano and turf algae.

    Try to get it(the turf) to grow in a scrubber / or add a nice amount of good GFO (rowaphos / bulk reef supply high capacity gfo is excellent to and lasts up to 3 months)

    OR give your macroalgae more light if you have them in a refugium so they grow more aggressively starving those in the tank

    It is often a slow process takes 1-2 months if one does it right plus 25% water change a month with good quality salt mix and R/o

    You can also add some red legged hermits they like that turf algae and mexican turbo snails

    See what I meant about phosphates and vodka? Im not so sure that the skimmer really pulls out that much of po4.. Im dosing vodka, but I have some GHA, also some of this brown algae like you on my substrate. My cheato is growing fast as well
