I'm currently running a 56 Column I bought from a friend with no sump and everything is HOB. Its messy looking, cables are visible all over, but all in all I still enjoyed getting it going and having my reef. However, we are selling our house and I was told I get to use some of the profits from the sale to upgrade my tank for the new house. I definitely want to go over 100gal, maybe 120+ or so and I want it have all the bells and whistles. It is worth it to buy the Red Sea reefer tanks or are you kind of just buying a name? What accessories really matter, like should I get a refugium, reactor, scrubber, and a skimmer or is getting all of that over doing it? What is a good optimal "under the hood" setup and do any retailers offer that built in to their cabinets? I'll be doing some of my own research to try and figure it out as well, but I'd like to hear what you all have to say, thanks!
