well im not married yet, but im almost 19 and i feel like i am lol. she wants to custom build a house as well, and i told her i just want one room...... the rest can be the way you want it, but one room! lol. i think a room like that would be way better than having a giant tank with only a few fish in it, i can have multiple setups and make it look good. she wants a saltwater tank so i can put a pink fish in it (royal gramma). but yeah thats what i want it to look like. and having one tank on carpet isnt that bad, but id rather have one than all of my tanks..... thats where im leaving a cement floor in right there. the basement is my haven, which is where this will take place. im assuming that canister filters are in an order for this setup? i think that by doing this i can have tanks and not show all my equipment, but just having viewing pleasure.....
