Monthly upkeep costs for your system?

[zum14]

Hello again. Its been just over a year since I liquidated everything and got away from this hobby. I can say with certainty that I regret that decision greatly. I have been pondering for a while and creepin over everyones tank journals checking the updates and getting some more ideas. I learned a lot the last time I played around in this pool. Went way too big to fast (cost waaaayy too much) and then tried to setup a small system that was a little too restricting. I am drawing up some ideas but I am trying to plan this one properly. Im trying to stay resonable but if I cant afford a decent sized system I think I will be setting myself up for failure and would like to avoid that this round. I would love to setup a 250+ gal reef tank with a basement sump but thats just not resonable for me at this time in this house. I have been thinking around 120 gal or so maybe 180 if the wifes in a good mood, maybe a 90 if costs are too high, but am trying to guess monthly maintence costs of a system of this size. I think this will end up being a FOWLR but im sure a few corals will make it in to the mix if they survive. I know people try not to think of this (when I did a search the only threads I found was from 2008 ) but im really trying to plan this one right. Im not intrested in the fish/coral new gadget expenses or setup as that varies greatly. Thanks to everyone, answer or no answer, great group of people helping out here.
