    Im not a salty person but the tanks so new, could it be diatoms? if so, it goes away in time as the tank matures...if its not, im sure other salty members can offer more info

    I just read about this not even ten minutes ago. If it's a new setup sometimes there will be brown "silt" on the sand after a while. It is supposed to go away just as quickly as it appeared and is not a problem. If it's not a new tank then I have no idea.

    It's called diatoms. It's algae that usually grows on new tanks as it cycles and sometime on mature tanks.

    Yes it's diatoms and tends to happen in most tanks, new and mature. You can combat it by addidng a diamond goby or other sand sifter to keep the sand clean (providing your tank is large enough). Also, your can turn the sand gently and some nassarius snails will take care of it.:;2cents

    Keep in mind that not enough water movement inside the tank will also cause this. If it's low water movement it will not go away it will only get worse till. Easy solution though, just add power heads, that will make it go away in matter of days (2-4 days).

    my sand has this troubel all the time, and my cleaner shrimp has the rest of the tank to clean without having all this trouble to look after, I've never heard of a diamond goby, but i may look into one if i like the look of it, thanks reefdude
