I was thinking about trying what Geoff did, and cutting some stuff up and making it all in one. I have been watching som stuff on you tube to try to make the best tank I can, but it looks like I might need to do a double tank. so Tim or Geoff, or any one for that matter, what do you think will be best for the 10 Gal, a sump, or refugium? as for hiding the other tank with a stand, I will most likely build one, it won't cost too much. so, just so we are clear, if I build a 3 chamber sump, do I need a protien skimmer? I really don't want to put all that money into it, seeing as how I will be getting a really good light for this thing?
