A foreclosed home down the river from me has been totally wiped clean and winterized except for one thing - a 6' long by 2' wide by 3' tall in wall aquarium! Is this too big to be practical for a reef tank? I'd love to have a reef but I'm afraid the lighting, reactors, everything would be bigger and have a way bigger price tag than my 20L reef! Anyway, I was just excited and wanted to get some good ideas for what to do with it - or if it'd be too big to reef it.
