    Could be black algae. Can you take a pic. Also what water did you use to wash your sand?

    hmmm naughty, that could cause hassels as tap water can contain a number of undesirables in it:(

    best to post a pic on photobucket.com and then copy and paste it in here (or esle bug viper, he loves telling people what to do, and might help:))

    i would just re rinse sand with water with some iodine in ,but swirling around with hands to loosen black stuff,, doing final rinse with sea water. when you put it back in tank put wavemaker over it to keep flow above normal and keep it in dark. for first two weeks, ps get a little sand from a mature dsb to seed it,

    You only need a light if you wanna grow macro algae like Chaetomorpha (called chaeto) on top of the DSB, otherwise no light needed.

    If you wanna grow algae, a 6500kelvin daylight energy saver globe will work.

    most likely some sort of cyano. Im sure without light it would be pretty dark in color. Stirring it up would not be a good thing IMHO, it will spread it thru your display tank. If it is staying down in your sump and not traveling, that is a good thing. It is where you want it to stay. My sump (refugium) contains alot of cyano, aiptaisia and im sure lots of other undesirables. As long as they stay put, then the fuge is doing its job.

    I suspect that it's caused by manganese oxide, manufactured by anoxic bacteria - the dreaded sulpher dioxide containing "black zones". I further suspect that you had some nutrients in the sand and/or on the bottom of the tank (if you did not previously have sand).

    This is not something that I would be too concerned about - just leave the sand undisturbed, and the black layer will eventually shrink in size (although it might not disappear totally). This is pretty normal for a new DSB.

    I had something similar happen in my old tank, I just left it and it went away after a while, a while being a good few weeks. Here's a pic of mine...
