I'm about a week into cycling now and i have noticed over the past few days that my rocks /sand have been getting covered in some kind of brown stuff. Is this some kind of algae? or what is it? I guess since my tank hasnt cycled yet cant add the CUC. Do i just continue with cycling process and get cuc after cycle to clean this up? What should i do about this brown stuff, and how do i get it to go away? and what causes it? thanks!!
