I agree with Fraggin, it looks like sponges, although it might be Coraline algae; so it is good, whichever it might be. Cyano algae (a bacteria) is usually magenta (deep red, almost burgundy in color) and can easily be sucked out. Not to be scrubbed, as earlier noted in this thread, because the more you disturb bacteria, the further they might spread. It won't be nearly as harmful as it looks, but does require sometimes drastic (chemical/medicinal) methods to remove completely.Originally posted</a> by maemae

Cyano grows in sheets that lay loosely on the rocks and gravel. It's very easily sucked or blown off with a turkey baster.
I just got rid of it by medicating after 4 weeks of cleaning it out every night, now I'm dealing with the side effects of the medication.

to get rid of cyano just do this, turn off your light for three days and dont let any sunlight hit your tank, then on the fourth day just turn on the actinics and then of the fifth day regular lighting schedule, good luck

I have the medication but if the UV or purple or what ever you guys call it also helps kill it?
Here is a side snapshot of my tank with that uv light on:

the paper work that came with the light was really lacking any real good info.
