Hello, I own a 55 gal marine tank with corral and live rock, its been set up now for alittle over a year. When I bought this tank, it was our first jump into marine tanks, so its a smaller 48x13x20 tank, I am wanting to upgrade my tank to a larger 72 gal. bow-front that is 48x18x23. My question is how to go about doing this without killing everything in the move? I plan to use my current lighting setup and live rock, and stand, can this be done, I know it will take time, so I am looking for some ideas, thanks
