I gave it an honest effort searching for this thread or postings pertaining to the title. SO...I'm looking to get my lady a Biocube or Nano-cube. She loves them and is probably even more excited about reefing than me. That said, we are both new to SW but not aquatics. Are there pros/cons between the two or are they basically the same in quality, maintenance, and sustainability? Just looking for some informed opinions, not looking to start a war.
