I'm in the process of building the stand for what will be my first reef tank. I'm planning a 75 with sump, skimmer etc...and I was wondering if it is possible to seal the system to the extent that evaporation will me minimal. The people at my lfs say that I'll need to add a gal per day due to evaporation. If that's the case then I'll never be able to take a vacation again and my wife, who is from europe (they like long vacations) will never let me set this tank up. I was planning a top off system as well, but I know that is not a "miracle cure" for evaporation. I have friends who would be able to tend to the tank when I'm gone but asking them to come over everyday might be pushing it.
Thanks
