Yea I agree with NL146. I also just started my 14g biocube for a month with dry rock and seeding live rock. Neon green algae throughout that appears to be calcified like coralline (maybe it's green coralline?). Snails and hermit seem to have no interest in them. They are probably benign.
Just dropped by today since I live only a mile away. They got the 220g loaded up with some good looking coral! They still seem to be in the process of organizing everything. Certainly shaping up to be an exciting place to shop.
