There was only a minimal amount of space to work with, so 100 gallons was about all we could do, or we'd have to give up some deck space, remove a tree or do something more complicated. As it can only be used half of year due freezing, small was fine. This photo is after I moved it from its full sun location (too sunny & too hot) to the other side of the deck, where it was sheltered from the sun by a gazebo.
