Thanks for your candor and opinion. I've got a lot to learn. I've been doing a lot of research for a couple of months now on tanks, systems, corals and inverts. I'm really interested and read as much as I can and I'm trying to make an informed decision on what road to take. I hope you don't mind the questions --- Here's what I'm thinking of doing: I like the TBS "package" and would like to go with that, I beleive. If I do, I wouldn't really need the bioballs in the back of a nano, right? My thinking is that I would need carbon and a skimmer and maybe turn one of the chambers in the back into a refugium (use live rock? macroalgae? something else?). I think that would help with the filtration. As for skimmers, are the skimmers that fit into a 24 gal nano adequate? Can you recommend a skimmer for the 24 that's not overkill, affordable, yet plenty of bang for the buck? Aside from the tank with plenty of lighting, can you recommend any other equipment that I might need, for example an upgraded pump (aside from the obvious test kits, heater, etc, of course) Right now, I have a freshwater 20 gallon that I pay a ton of attention to. I live in a rural area and the LFS is nice, but overpriced in my opinion, so I need to buy online (as much as I'd like to support the LFS, my funds are limited). Still yet another option I'm considering is to just forget the nano tank, get a 20 gallon tank and sump and go from there....but I like the all-in-one concept since I don't have a ton of room....your thoughts?
