   what is this?
   Very easy to remove yet comes back quickly.
   I recently downsized to a 29 Biocube. No skimmer as of now, standard PC lights, low current. 
   Thanks for the help!

   Any one of a number of various algaes. Check out sites like chucksaddiction.com or melevsreef.com for a possible ID. If it becomes a problem then look at your nitrates and/or phosphates.

   Wow...that stuff is weird! Looks like a green version of cyanobactera. Never seen it before. +1 on the above mentioned resources.
