The largest tank I have ever owned was a 225 gallon aquarium that measured 72”L x 30”W x 24”T. It seemed like a big tank and I was not gung-ho about going bigger with this new tank. A bigger tank equates to more money for the tank, equipment and livestock and I didn’t want to go overboard.
225 gallons seemed like a good size to me so I started to play around with the dimensions. What about the width? Width or depth is so important with a reef tank since it really opens up so many options in terms of aquascaping. I always say you should go as wide as possible and for this tank I wanted it to be 36” across. How cool would that be, I thought, for a peninsula tank.
