sweet.. then the maroon i have isnt what you have it comes off.. real easy ... so is it bad.. and should i just let it go or what..
Yep if you can blow it off it is most likely Cyano. In our home tanks the most common color we see is maroon or dark red.......Do a search here on the Forum for Cyano or Cyanobacteria , lots of info.
In Reef tanks good strong water flow, good prams and sometimes a reduction in ligh levels for several days will help starve it out. Along with hair algae these are the two of the most common early tank set up issues that we incur.
Here is a link with some general info on it..............
