Another reason for the huge range, is because there is a difference between circulation in the tank, and circulation through the filter. The saltwater/reef community seems to be moving to powerheads in the tank providing a 10x (or even greater) turnover within the main tank. However the filter is on the lower, more managable side at about 5x. Allowing its media more contact time and the ability to use lower power pumps.
On the same token, such a small tank, and stuffed full of plants, you may not even require a filter. Just a power head to push the water/nutrients around may suffice. Though I personally would always want some dedicated filtration.
